Uhm wat dis? If you think that gen Z people are more racist than the previous generations, then you have probably met with the minority. I rarely know a gen Z racist fella (I'm gen Z too). Tiktok could be true, but my friends definitely don't use Tiktok and millenials use that trash site just as much as us, or maybe even the boomers too idunno.
If you grow up in the US, it's pretty hard not to be racist because the entire culture and history is steeped in racism.
It's taken willful self-reflection to recognize some things I say or do that are implicitly racist. If we just went about chanting, "I'm not racist," we'd never be able to grow and improve.
