The Takei case has been relatively quiet. I have no idea what the truth of that matter is, but it would not surprise me if Takei and Spacey are getting relatively less attention an account of being gay. There are undoubtedly some portion of people who (either explicitly or implicitly) believe that “the gays are just promiscuous deviants anyway, and that’s just what you get for turning away from God”, or some such rubbish. I don’t endorse that view of course, but it wouldn’t surprise me if there are people that do.
From a strategic perspective, I think that focusing on women is probably a better approach to take when engaging this issue. There are going to be some old-fashioned sexists that think about this issue purely in terms of “protecting the women”, which is a gross framing, but I think it’s probably a good idea, strategically, to get as many people on board as possible regardless of their ultimate motivations. Let’s all agree to stop the sexual assault first, and we can argue about why later on. I think that any progress made to reduce predatory behavior will eventually help everybody.
