Roz Kaveny in The Guardian:

Twitter has been flooded with controversy for the last week about the RadFem2012 conference, currently booked into the Conway Hall, which announced its membership as restricted to "women born women and living as women" (it originally said "biological women", but that got changed after much mockery). This disturbed the trans community, which it is meant to exclude, but also those feminists who regard trans-exclusion as something other than radical.

[...]

One of the problems with the Internet is that it is possible for people to lock themselves further and further into a restricted mind set where they hear no other voices. On the other hand, it makes it possible for those with a strong stomach to overturn every stone and find out just what people are saying and thinking. It's clear that Jeffreys and her supporters are very hurt and disappointed that so many younger women don't agree with her – Jeffreys blames the corrupting influence of post-modernism and queer theory; "trans-critical" lawyer Cath Brennan - who uses Twitter to deride trans people's experiences and mock non-trans feminists who are their allies - is also a RadFem2012 attendee.

Of course, the trans issue is only one aspect of the conference. Its mission statement makes it clear that this is a "female-only, activism-focused conference with a radical feminist agenda". Space will not be given to anti-feminist sentiments, which is arguably another way of saying that, on most crucial issues, the party line is predetermined and that any dissent from correct "radical feminist" thinking will be stigmatised and driven out. Jeffreys makes it clear in many of her writings that post-modernism and queer theory are the enemy, and that piercing, tattooing, BDSM and role play are all pollutions of a feminism that is nothing to do with choice or preference, everything to do with commitment. Indeed, the Radical Feminist Hub, to which she contributes regularly, links to resources arguing that what it calls "penis-in-vagina" sex is a bad idea, from which women should choose to refrain.

Or vice versa.
