When I read the stats the other day that only .5% of rape cases result in a conviction it put into stark light the concern with the stereotype that white women make rampant false rape claims. Charge people who make false claims, but keep the numbers in mind. This is a rare phenomenon on par with false claims of other violent crimes. I don't know if anyone has even studied the comparative incidence of false claims by gender or race so I don't know whether the stereotype is based in anything other than the exceptional instances (which generally aren't about rape anyway) that make national news.
I think the line also gets blurred when people call women "Karen" for speaking up in cases where there is a real grievance.
