The founding fathers debated the merits of war over and over until they decided to go to war with England.
It seems un-American to deprive the type of speech that founded this country and conflate it with actual violent speech, examples being "people need to start killing people in the streets". That would be an example and I'd be right there with you. Or saying "someone needs to do a gary plaunche" or whatever that guys name.
Laying the philosophical justifications for why a civil war would be preferable to the continued rotting of this country is the type of thing politicians would debate about; this is not at all the same as someone encouraging vigilantism or any other sort of lunacy.
EDIT: Moderator messaged me back as to why what I said was not prudent, and he made good points and in fact out-philosophized me, noting that the founding fathers wanted to avoid a war and only agreed to it when it was unavoidable. He also pointed out some other things that were worth considering in terms of the wisdom of his rationale so I feel the moderator was completely justified. Being vague because it's his private conversation and all that needs to be noted is that he brought up wise points I didn't consider.
Signed: totally not the moderators alt!
