It's not just the caucus, it's ALL OF THEM. Conservatives come off, to a person, like a Borg-like hive mind. They ALL "argue exactly the same". It's becomes truly freakish once you've seen 50+ different people not just arguing from the same set of talking points, but arguing the same WAY.
First and foremost, if they believe you're liberal, they will never, ever, ever admit they're wrong or that you've made your case, about anything, ever. Even if they know they are themselves full of shit, it's more important to annoy the liberal they're speaking with over anything else.
The corollary to this is they have absolutely no concept of intellectual integrity, or if they do, they assign it zero value. Logical consistency is for suckers and losers, or so they seem to think.
They also either can not, or will not, understand analogies, esp. if you refute their argument via analogy. They'll find some totally illogical reason why the analogy you've made, that lays bare their fallacious reasoning, is really NOT equivalent, even though it absolutely is perfectly equivalent.
And when all else fails, they just move the goalposts and/or impugn your source(s). Like WITHOUT FAIL in these past 28 years. EVERY SINGLE ONE of them does all of the above, and the consistency is uncanny. IF they think you're a liberal who's arguing with them, their entire goal in the conversation is to annoy the shit out of you, and never give you the satisfaction of hearing them say "you've made your point", "I guess I was wrong", etc.
