Right, that same social conditioning that transwomen had, you know the whole having grown up with a penis thing, large percentages of transpeople never do any hormone therapy let alone other options, so you should account for these, a transwoman who has no hormone therapy is a man except by self classification, you seem to want to gloss over this. However pointing out that socialisation is the cause of violence isn't the best foundation for your argument about transwomen (who will have had male socialisation) not exhibiting same violence tendencies as men.
Also not 'cis', no need for a classification of everybody who is not trans, I do not have a label for being not-diabetic or not-anorexic, women/men and transwomen/transmen does perfectly well. Being as vaginas (and penises/prostates) are a thing which medically needs to be looked after and the incubator/inseminator is a useful division, from a medical point of view.
The whole notion of masculinity and it's very narrowly defined ideas is more of an issue, as is male violence.
Just in case you were wondering I am male born with a penis and have questioned myself much over the years, that blog helped me see a different opinions on this. I can see merit in radical feminism, that beyond has penis/has vagina (and associated issues with those) gender really shouldn't mean anything, you want to wander round in a dress, it shouldn't be limited to those who have vaginas, want to go get shot at in war, shouldn't require a penis.
Conflating the social construct of gender with the biologic reality of gender is not helpful for society. It harms both women and men by making us fit into boxes.
And I would remind you that as always people are awful.
