I think he genuinely thought they'd accept him with open arms just because he votes red, even though he has zero things in common with them besides that.
AntH isn't conservative by any metric. He's not religious, nor a family man, nor a community man, or even worthy of the title "man" at all. He's a self-admitted recluse whose hobbies are childish and insular. Video games, poker and karaoke instead of fishing, hunting and doing handiwork. He's a vulgar, degenerate woman-beating substance abuser whose every fiber screams "urban white trash".
He has no fundamental objections to gays, trannies, drugs, government overreach, mass corporatization, taxation, mass immigration, illegal immigration, Green policies, or anything else a classic conservative
would probably oppose; except when they happen to inconvenience Nana personally, then they're the worst things in the world suddenly.
The only attributes that even remotely qualify Tranth as right-wing are his infantile toying with firearms, and his visceral hatred of F/Ns. Both of which just make him look like the most cartoonish stereotype of a Republican a deranged leftist could come up with. If anything, those seem like traits that would only make a respectable conservative want to disassociate himself from this pockmarked degenerate.
Can you even imagine Nana at some country club or something, trying to rub shoulders with the local business owners and stuff? What the fuck would they even talk about?
