When a person of color, especially if they're black like me, affirms their support for causes such as queer liberation, feminism, animal rights, or socialism, I immediately feel that I can believe, with minimal doubt, that they're truly convicted and principled in what they're advocating for.
However, when a white person claims to support leftism, until my skepticism is proven wrong, I immediately assume they're a dishonest and performative libshit. I then proceed to interact with them with hefty amounts of caution. If my assumptions are proven true, I'm never shocked.
It's quite astounding how they pick and choose being progressive as if they're picking out ice cream flavours instead of doing the normal thing of supporting everyone equally.
