I'm not sure whether your first sentence is meant as snide, but given the quality of your posts on gender issues in general I'll assume you're just taking the opportunity to elucidate the logic behind both viewpoints.
I do have to say that as a person somewhere on the trans* spectrum some of those posts do feel rather hateful towards 'my kind' though.
You specifically posted links equating radical feminist concerns with queer theory/transactivism with "transphobia," cheapening real transphobia, given that the links I posted (have you read them? I recommend them) illustrate that "radical feminist" desired exclusion of transwomen from conferences, etc, is not motivated by hatred, but a gender politics that doesn't have much to do with queer theory/transactivism specifically.
If you think I'm saying bigoted things (or trans*-spectrum-phobic), I'd appreciate knowing where I've done that so I can learn not to.
I simply shared two wikipedia articles on the topic to refer to a somewhat impartial source and added an article which illustrated the existence of a transphobic fringe within the feminist community.
I didn't intend to make any statement concerning exclusion or condemnation of transwomen from conferences; although it seems like you did jump to that conclusion. Neither did I explicitly mention 'radical feminism.'
As for feedback; the part that's hurtful here is that while the article I posted seems to take great care to attempt to perform a level-headed in-depth deconstruction of transphobia in the feminist community and painstakingly ensuring to criticise specific behaviour by specific people rather than the feminist community as a whole.
Many of the articles you linked invoke a variety of ad-hominems, strawmen and generally mostly seem aimed at eliciting a certain emotional response towards the trans community.
Actual transphobia (like the rampant homophobia, specifically against lesbians, before it) in "feminist" communities is tragic, just as it is anywhere. I don't mean to excuse bigots, only to provide context for the discussion of the political exclusion of (rather than emotional, bigoted marginalization and violence against) transwomen from women-only spaces, which is the overall topic at hand here and the concern of many radical feminists.
As I suspected we're mostly on the same page then with the main difference being (if I'm correct) that I interpreted radical feminists as the subset of feminists who hold radical beliefs rather than referring to a specific 'radical feminist' belief system and its views on trans* issues (whose existence I was not aware of until now.)
