Hi @Juells, Masoud is quoted as saying some transgender people are “bullying lesbians into having intercourse with people they don’t want to". Now, I followed the link to that Tweet, and I don't think she's made any effort to say "some".
I think Masoud is deliberately general with her comment, whereas James goes to great lengths to express that this is a problem caused by a minority. He doesn't need to make it a problem of all transpeople against all lesbians in order to make us see that it is a problem worth confronting.
As for Kathleen:
My own view, for what it is worth, is that there should be a separate political and charity-based movement for transgender people, which is not attached to those people defined by sexual preferences.
I simply disagree with her personal opinion, based on the experiences of those close to me within the LGBT movement (they are mostly L and a few G). I don't disagree with her holding it, and Kirkup does very well in pointing out "There is, I dare to suggest, no single lesbian opinion or lesbian community, just lots of different people who think different things.".
