You’d like to think that, but I’ve heard multiple people say “better wrong than liberal” without any sarcasm over recent years. This is absolutely a belief of some.

Poe’s law: on the internet, it’s nearly impossible to tell.

I really doubt it. Have you seen reality? I wish the whole thing was satire.

I’ve seen it enough that it could be a meme or it could be a disturbing trend.

it was some dude on Facebook responding to a post about fake news

I don’t think it was satire

even if this specific example were, the law of large numbers means there’s a very high likelihood that at least one person really holds this attitude.
