I actually debate liberals on Facebook on places like the Des Moines Register. It's always the same schtick. Start out with some lawyer parsed politico double speak, usually morality and not logically based, all hissy and bristling with seething passive-aggressive anger. Really play the alt-church bitty persona.
Then you challenge them, picking the contradictions out. Then come the slurs. Bigot, intolerant, *-phobic, among many.
Then you point out how religious and judgemental they sound, and they escalate. Next your trying to gang up on you, cyber stalking, doxxing, threats to report you to FB.
Challenge them more and they escalate again, with various kinds of physical or legal threats, implied and explicit. Then come the more generalized slurs against conservatives needing all to be shot or put in camps, genocide, torture, you name it.
And that's where it almost always ends up - rounding up their enemies and eradicating them. Just like lefties have done for centuries. If not directly then implied. It's like there's this beast inside each and every one one to eliminate anyone who disagrees with them. Very very few are actually pacifist.
