Either A.) they don’t want to actually debate the topic but hurl insults, or B.) they have been eviscerated before for making weak arguments.
I have seen plenty of conservatives show up here, engage in actual debate without crossing community guidelines (and the guidelines say nothing about politics). Usually they give up after a while when their arguments are countered.
But it’s easier (lazier) to just create the self-fulfilling prophecy.
I know some conservative sites that are far more keen to censor political points that counter their own narrative.
