Liberals are basically a cult at this point, I honestly don't think it's possible to engage with them in a meaningful way. They've basically constructed a narrative regarding how the world works, and anything that doesn't fit into that narrative gets discarded. Amusingly, libs are able to recognize this behavior in other cults like qanon, but are not able to apply the same analysis to themselves.

I suspect it's going to take a crisis that affect these people in a tangible material way for them to start questioning their beliefs and examining things in a critical fashion.

And the types of replies in that thread are basically a learned behavior where libs just dismiss things they don't want to hear and expect the rest of the libs to pile on to downvote.
