Slavic slaves in the Roman empire predate the social construct of whiteness. Implying they were oppressed because they were white is one of the stupider things I've read on the Internet today.
Okay, modern day. Look at the DEI initiatives. Literally just systemic racism against white people (and Asian people, but thats not what this argument is about), thats why they keep getting slapped down in court, and now having laws directly passed against even teaching them because they are so racist.
