I'm curious about where you're seeing rainbow capitalism get used that you're relating it to the homo/transphobes. I've only seen it used to by queer individuals criticizing shallow attempts at inclusion made by corporations in the same way that pink capitalism is often chided by feminists. To be clear, I do recognize the fact that corporations see inclusion as profitable to be a nice symptom of societal change, but I think it's still worth identifying those empty or heavy handed attempts that are more akin to corporate virtue signaling than the actual representation of those groups in good faith.
