Why do feminists on GS almost never cite facts in their questions/answers?

I'm not accusing them of this, simply because I disagree with them. On rare occasion, a feminist will say something genuinely thought-provoking. It might not change my mind, but at least it makes me think. The problem is that this almost never happens. Ninety-nine percent of the time, it's just the same old vague complaints without any credible evidence. If misogyny is so rampant, why don't they give some specific examples of it?
