Transwomen are human, as such they are prone to all the varied traits of humanity, not some select goody two shoes version of it.
Only... they are also laden with male biology which makes them part of the more violent / aggressive half of humanity. That's not saying they are inherently violent / aggressive, it's saying they are biological men and thus more 'llikely' to have those characteristics.
Although they might believe they are women, and have womanly feelings (whatever the hell those are), they do have a male body, so damn good proportion of their 'whole' is male. So even if they were somehow a little more passive, it's still a hell of a lot more male than a biological woman (aka 'woman').
Women don't usually hate men. They usually hate some of the behaviours and attitudes on some men.
People don't usually hate trans. They usually hate some of the behaviours and attitudes of some trans.
It's not transphobia, it's anti-wankerism.
