blud is gonna crash out at toddler calling them or someone else fat and stinky with that "fatphobic" point lmao
But seriously, there certainly is a degree of classism and elitism - I remember there was a quite popular post after Trump got elected that basically showed how if people with higher education only were allowed to vote, then Kamala would have won, and the comments went how you'd expect them to go. The sentiment can still be found today in lib news threads, though they are much rarer since Republicans are no longer the hot topic and now it's ICE or whatever.
Though to be fair, it probably has less to do with them hating the poor, obese or people who didn't go for education for any reason and it's just a product of the team sports politics bullshit the vast majority are knee deep in. Gotta cheer your side and throw any insult you can think of at the other!
