For instance, I have an aunt who is definitely MAGA, and is flirting with Q-Anon ideas. However, she has pretty good views on the environment and animal rights. For instance, after travelling to Ecuador, she donates to some Ecuadorian land trust run by locals. However, if you start talking to her about the border or gender, she goes full Orbán.
idk, your uncle sounds like he has contradictory beliefs for sure... but other than the standard boomer shit that sucks, like homophobia and racism, he sounds way cooler than like 90% of the people I know in the imperial core.
the coca-cola conspiracy shit is awesome. its like a communist version of fluoride conspiracy theories in the US that cause dental carries, except the end result is dissuading people from drinking shit that is actually horrendously bad for their health anyway. Your uncle is fighting type two diabetes and an American symbol of consumerism all at once. o7 o7
