Eh, I've noticed not that at all. In fandom spaces, white people who are part of a marginalized group tend to be extra apologetic of their whiteness and even downplay their marginalized status. "I'm trans but I must make it clear that I'm white and I'm aware that I will never ever know the full extent of transphobia because I'm white uwu uwu uwu" and the like. And if they ever do call someone out on real transphobia (or whatever other -phobia affects whatever their marginalized status is) they're met with "Why do white people always have to find a way to be a victim somehow?"
