[EX Q]: Crisis, hardly. The only ones that did cry, were Bill & Hillary. And yet he was punished by the act of disbarment. All the while, those "family values" Republicans;  Newt Gingrich, Bob Livingston, and Dennis Hastert that were sitting on the impeachment panel should have recused themselves for similar or a much worse offense. The initial charges never rose to the level of full impeachment. Get over it.
[EX A]: No

[EX Q]: There is no need to impose a sales tax on food items or medicine. All other items are fair game regardless of where a person lives. Buying is a personal decision. If the tax bothers you, don't buy!
[EX A]: No

[EX Q]: I see the user guide above, but does Civil offer any advice on what should be flagged? I see three options in Flag: "abuse/harassment, spam or threat to self or others". Those last two are fairly clear, but I can imagine disagreement on the first. I'd be interested in which of the comments below rises to abuse/harassment and I imagine there is disagreement within commenters. 

A. "This is a horrible idea".
B. "This is the dumbest idea I've ever heard of and anyone who supports it is doesn't understand the underlying issues".
C. "Anyone who supports this awful idea is ignorant".
D. "Anyone who supports this awful idea is an idiot"
E. "I can't believe you support this idea- you must be an idiot".
[EX A]:
Yes
