Wait, intersectionalism is considered bad by people who aren't right-wingers? I thought that just meant acknowledging that different forms of discrimination can overlap with each other.
That's what it means in theory but in practice it means complaining about white people wearing hoop earrings or dreadlocks or eating Chinese food.
If by in practice, you mean a handful of people, sure.
It's actually really funny how single incidents get more attention than they should. The reality is a lot more complex. I encourage you to watch Contrapoints on YouTube, specifically his take on cultural appropriation (spoiler: he agrees with you).
