bullying and classism is far worse here than in the American and Canadian school system
There are some contrary views on that. Historically, I'd have said that U.S. school culture has some of its own conventions (school proms, a significantly higher emphasis on competitive sports) that create their own conformist orthodoxies which are ripe sources of bullying. Historically, because some of those things are now being copied over here. The U.S. education culture also preserves some unfortunate school-age concepts into higher education (exemplified by fraternities/sororities) that can make people feel still trapped in school culture where U.K. universities are more often an opportunity to escape that and reinvent yourself.
You can see some of the experiences and attitudes that led to Incel culture in that linked Slashdot article and the responses.
Maybe not, and yet bullying and classism is far worse here than in the American and Canadian school systems. (Anecdata; I attended schools in the US and UK)
