wow, that person is a massive jerk. the "white people cant be victims of racism" falls apart when you look at how nazi germany treated jewish people. Has this person also seen how Russia treats the Ukranians, who are STILL victims of a brutal genocide and apartheid occupation ? They should educate themselves before they run their mouth. I'm a minority member and I'm VERY angry at them.
I suspect they'd say something like, "White people aren't oppressed for being white, ergo Jewish people are NOT oppressed for being white because they're oppressed for being Jewish." in response to that.
But the thing is, being white won't exactly save you from antisemitism. Jewish people exist in EVERY race, likely just because the religion is so old it just kinda got around eventually (you're not allowed to proselytize in Judaism, but you ARE allowed to convert to Judaism if you want to, and Jewish converts are real Jews), so of course white people can still be victims of antisemitism, and downplaying their suffering just because they're white is callous at best.
Plus, it also ignores people who may not be discriminated against because they're white, but rather because they are the "wrong kind" of white. Italians are famously discriminated against by many other Europeans for being Italian. Germans saw a spike of hate crimes against them after WWII. Irish people were also discriminated against for a solid portion of British history. Pretty much ANYONE wearing a turban or hijab will be hate-crimed due to islamophobia, even though pretty much every religion has at least some white members. Ukranians are another good example!
Like yeah, white people are not typically oppressed just for being white, but that doesn't mean white people can't be victims of racism or oppression based in racist assumptions. As that other person said, the catagories aren't actually real, it's the OPPRESSION that is real, so of course oppression can affect people it technically didn't mean to!
If anyone is wondering btw why I keep specifying that white people are not oppressed for being white in the west, it's because white people can actually be discriminated against if they live in a non-white majority country. Japan for example is famously nice to white people IF THEY ARE VISITORS, but white people who live there as immigrants famously ARE oppressed often simply because they're white. Yes, black immigrants usually have it worse due to colorism, but that doesn't mean white people are just let off the hook. You could say that visibly East-Asian people in Japan have majority privilege.
Oppression is a complicated beast, so trying to streamline it like it's simple just doesn't work. People who were caught in the crossfire were still shot, after all, and people who died of gunshot wounds still died of gunshot wounds even if that shot wasn't technically "meant" for them.
