"Assuming a pill exists that compels the user to tell the truth, THW destroy it." — Recent fun motion
UPDATE FOR COLUMBIA 2022 (VPF)
Read the following sections: Overview, General Paradigm, Miscellany and Weird Aside on Evidence -- all else is Parli specific.
Relevant information for PF: I have a strong distaste for theory but as per modern paradigmatic standards, I'm happy to evaluate it as warranted in the round.  The bar to convince me to pick up or drop a team on a theory call is likely pretty high.  I will tank you if the theory is strategic and not based on something reasonable.
Regarding evidence in PF.  I actually debated PF some in High School, I'm not unfamiliar with evidence and carded debate.  The maxim that evidence doesn't replace warranting is still true, though, and I will reward better warranted arguments over better carded arguments assuming the belivability of the claim is constant.
Ask me questions before the round if you have questions -- I'd love to get to know you as well -- debate is a game, but we are all members of the community of debate and I'd love to foster that as much as possible.  Ask me questions about college debate if you're a senior (or not) -- I'll connect you with the debate team of your institution if you know where you're going etc.  I love verbal RFDs so will probably give one.  I don't understand PF speaker points so take those with a grain of salt.
I don't claim to be an expert in PF or anything close.  I do understand argumentation, warranting, impacting, weighing, etc, and want to see all of that in a round at the highest quality possible.
Parliamentary Debate
If you read nothing else, read this: don't spread; don't tag team; keep stuff in your time; be wary of theory; impact; weigh; warrant.
Overview
I debated for four years as a student at Stuyvesant High School and currently debate APDA for Columbia University. I have experience teaching debate to middle school and high school students, I tab way too often, and have lead more judge orientations than I care remember.  If you care, I'm the president of APDA, the oldest and best college debate league.
People tend to care a lot about these paradigms — I really don't — if you have specific questions, ask me before rounds, in GA, whatever. Please do ask if something is unclear!
I run whacky cases, I debate whacky cases, I choose whacky motions — I really don't mind a lot if it's done well and respectful and conducive to a good round of debate.
General Paradigm
So everyone likes to claim they're a tabula rasa judge. I think this is nonsensical. Obviously personal views will not influence the round, but as arguments leave the sphere of the normal and easily bought, the burden of warranting well increases.
It's reasonably straightforward for me to buy, for example, that individuals do things that make them happy, and since eating ice cream makes people happy, people eat ice cream; but is comparatively hard for me to buy that actually, instead of eating the ice cream in my refrigerator, I'm going to make a 2 day trek across tundra to obtain some of the same ice cream.
I don't mean to discourage complex, strange, or whacky argumentation; rather, I aim to encourage elegant, simple, but robust warranting.
Theory
Theory has its place (LD / Policy / new PF circuit / your dinner table maybe ?) — and it's almost never in a parliamentary debate round.
Please limit any kritiks, theory calls, whatever else theory masquerades as nowadays, to instances where the use therein is warranted. Unless something is tightly or abusively defined / modeled or one team is engaging in reprehensible behavior, there is no need for theory — debate the resolution. This is an instance where I am certainly not tabula rasa, I will almost always, except in these previous instances, assume that the theory is being used in an effort to actively exclude the other team simply because the assumption is that I, as a seasoned debater, can follow it (which I can). Except in the caveated cases, the burden is on the team using a kritik or some other theory to prove to me they are not doing this.
If you want to argue about mutual exclusivity of a counterplan, or whatever else you want to do, please be sure to not forget to warrant, and explain things in reasonable terms. Just as you're not going to go off using advanced economic terms in rounds, and instead going to explain how a bubble works (hopefully), don't just use a pick, actually explain and warrant it. And on that, a counterplan had better be mutually exclusive, or at least functionally so, given certain tradeoffs.
Expect lower speaker points and to lose in cases of over eagerly applied theory.
Miscellany
I don't want to warrant for you. Don't make me.
I don't want to impact for you. Don't make me.
I don't want to weigh for you. Don't make me.
I am not going to get into what makes a warrant 'good' or an impact effective or weighing necessary, please as your coach, varsity, mentor, or email me if none of the previous options are available to you (johnrod.john@gmail.com).
The final two speeches of a round (the rebuttal or crystallization speeches) are NOT to restate every point in the round, but instead are meant to synthesize, weigh, and flesh out impacts. Please do that. The most effective rebuttal speeches focus on two to three levels of conditional weighing. I won't vote on some random unimpacted and unweighed pull through.
Don't spread — think about a speed a non debater would be able to reasonably follow. This usually means something fast, but not double breathing. Side note: someone who enjoys spreading please explain to me how this doesn't destroy the educational value in learning how to be a rhetorical and persuasive speaker please!
Instead of focusing on a breadth of argumentation, please focus on a depth of argumentation that is complex, and includes a high level of weighing structures and effective warranting.
Tag teaming — never seen this in parli outside of the west coast. Don't do it, you'll have your own chance to speak.
POIs — take them, use them, respect them. Don't go back and forth — if I wanted crossfire I'd be at a PF tournament. Seriously. Also, these are supposed to be fun and humorous — if you don't believe me, watch the House of Commons — however, you are HS debaters and probably take everything way too seriously, therefore I'll settle for not rude.
Offtime Stuff — No. You don't have to tell me what you're going to do, just do it.
Weird Aside on Evidence
Please don't confuse providing evidence with providing warrants. Simply because you were able to effectively use Google and find someone who said something doesn't mean that it's a) true b) important c) relevant d) it will happen again e) isn't without opposing evidence. Please always default to explaining why something happened, not simply that it did, or that someone believes it will happen again.
I have never once picked a team up for the quality of a card, and no round should ever come down to a piece of evidence in any way, shape, or form.
