Lets not make this personal.
I actually think there should be a rule about NOT making things personal from either side.
I have a friend who is heavily into the social exclusion of black people, predominantly in America, this is because he is an incredibly intelligent individual with a lot to say about the world but ALSO because he is black so the issues hit home for him.
I will often reply to posts he puts up on facebook, sharing my understanding or empathy of a situation and he will do the same in regards to posts I put up, mostly feminine issues.
At no point do I judge him for 'only' focusing on a few types of social injustice and neither does he, I would not dream of posting 'oh but think about all the girls in India...' when he has posted something he relates to and cares about.
Because that would be demeaning his point of view and his research. So why is that happening to feminists? Why do we have to consider the plight of trans women in America? Obviously it is a plight that people will feel strongly about and that people want to learn about (myself included) but if I choose to spend my time spreading awareness about equality in regards to females, why am I then chastised for not caring equally about other things?
If trans women want the plight of trans women to be known, they need to do that research and spread that awareness, not expect feminists to do so for them. Frankly the three trans women I have on my facebook are not at all interested in trans exclusion and are even less interested in female exclusion.
