all charisma and salesmanship is, to some degree, a threat

That's true. But when honest discussion of charisma is outlawed, only outlaws will have charisma.

Right now, a large share of male charisma falls into the hands of the "naturals." These men are disproportionately extraverted, oriented to short-term mating, and hyper-masculine / anti-social in personality traits. Of course, not all of these guys are assholes, and most of them probably aren't, but I think it's fair to say that they have a higher rate of assholishness. The only way to stop these men from commanding a disproportionate amount of female interest is to give more charisma to the guys who are more introverted, long-term oriented, sensitive, and prosocial in values.

To paraphrase William Gibson, charisma is already here, it's just not very evenly distributed. The only solution is to try to distribute it more evenly, and educate the public about how it works. In the case of male heterosexual charisma, it means educating the male have-nots, and educating women about what many of them respond to. This same principle applies to female charisma, of course.
