I'd be careful of that. There is plenty of evidence that abuse in lesbian relationships is as high as in straight relationships. I think when we assume that abuse in relationships is primarily a male problem we are whitewashing abuse by women and abuse in relationships where there are no men. Whenever I point this out it seems to upset a lot of people but that is not my intention. Interpersonal conflict and abuse in general is genderless so we should expect there to be abuse in relationships of the LGBTQ+ variety. The factors that contribute to abusive partners are much more complicated than just a "power dynamic". Further, power dynamics can exist in many ways that aren't exclusive to traditional masculinity.
