I guess that's part of the reason I hold him in such contempt- a lot of his comments have made their way into my Twitter feed, and I've yet to see something that wasn't either directly advocating irrationality (c.f. https://archive.is/xfjyi), blatantly speaking on behalf of the supposedly marginalized, or making uninformed statements on something or other.
No intelligent being should ever have the right to speak "on behalf of" any other intelligent being without their direct approval, any other standard is massively insulting.
Regardless, I genuinely don't understand the appeal of outrage-writing over subjects that simply do not concern you. For example, I'm straight but I'm also a proponent of gay rights - does that give me any right to speak "on behalf" of gays? Isn't the entire "I'm not [gay/black/a woman] but..." ideology of people stealing other people's voices exactly the reason some countries or communities have societal problems with various minorities?
