They can. The boundaries of what this opinion is permitted to be are defined by the self-reported experiences of women and of gays. You are allowed to have an opinion about a minority group, but it has to take the reported experiences of the minority group at face value as one of its foundations. It's utterly senseless to disagree with someone about what their own life experiences are, so any opinion which does so is illegitimate.
