Civility subsection suggestion

[brewer]

So where would the following response fall?
FU. It might not be your intention, but I think your statements make you sound like a homophobic dickwad. furthermore I find your position to be bigoted and ignorant. 

Is that over the line or under the line? Who gets to decide? And if its over the line, how is that dealt with?

Do you think telling someone "FU" and calling them a "homophobic dickwad" is civil?

That might be completely civil for some people, and I know some of them. Most people do.
