I feel like you have opinions here - that you think certain sorts of groups are more likely to be scared than others. I'm sure that's right, but wondering who you have in mind.
As a straight, white, fairly well-off, more or less neurotypical man, I'm sure I should be in all the privileged groups and so should feel pretty empowered. Maybe that's why I feel like I should be able to blog under my own name.
But I completely understand what OP is saying. I definitely have the fear, and I've toyed with the idea of having an anonymous persona before.
