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.
Nah, that's fair. Not all white leftists are grifters or liberals, but it's good practice to assume a baseline of distrust until proven otherwise. Source: I'm white.
