A Sometimes Unpleasant Person I Know

I won't name any names right now.
==Some unpleasnant anecdotes==
===The fallacious "you too" tactic===
Some recent examples:
Once (around spring 2016), I criticized the Trump wall, and he shot back "but you're doing the same thing to racists" or something, I had to point out that, no I don't advocate blocking racists from immigrating where they want to.  So I'm not doing the same thing.  At all.
And that was difficult for me, because it was so sudden and bizarre that I didn't know how to respond right away.  When I did, it took a bit of back and forth, but he eventually conceded.
Another time, I talked about an article which claimed that some Hillary email proved something.  But (I discovered after looking into it) it couldn't have proved such a thing, since the email was 2014, but the other event they say it proved she knew about happened years prior.  So it can't prove she knew about it back then.  Just because she knows the thing now doesn't mean she knew it back then.
After I said people need to look at the sources like that, he said "same with criticism of Trump" or something.  I said that the sources for criticism of Trump are often about things Trump himself said.  He (as usual) tried the "you too" childish tactic by literally exasperatedly saying "then you could just say Hilary is the source for criticisms against her too" and made this scrunched up incredulous face shaking his head with a little laugh.  But that wouldn't make sense, if he understood what I meant.  In no way would claiming "Hilary is the source for criticisms against her too" fix the logical flaws in the article I debunked.  And thus the criticism against her arose only from a logical flaw made by the critic, not from Hilary.  Meanwhile, Trump himself says things that are false, immoral, bad policy, and so on.
And again this was so sudden, hostile, adrenaline-inducing, and bizarrely illogical that I didn't know how to reply.  So his nonsensical outburst remained unchallenged that day, unfortunately.
