"British food is soooo bad/gross/flavourless"
All of it? Or just a couple of cherry-picked dishes mainly eaten by lower class families that you think are weird? Many types of curries are made/eaten by British people every day and those aren't suddenly "not-British" bc you've decided people with South Asian heritage aren't British or capable of contributing to British culture. "Yeah but South Asian people are only in England bc of colonisation :/" Are Black people not American bc many of them are there bc of slavery? Is soul food not American??
"British accents are soooo cringe"
All of them? or just the ones used by people who've been forcibly made "lower class" by centuries of oppression? these are the people who say "boht-ole 'o whot-arh" or "innit." The white ruling class you're supposedly mocking doesn't say that. It's poorer white ppl & POC.
but you know who else mocks/stigmatises cultural food they don't like and any accents (including British ones) they think sound funny/incorrect?
the white British ruling class. you are doing white British ruling class behaviour when you do this shit. stop it.
