Thank you all for your responses - I was busy but am back now. I can see that some of you feel I have some agenda other than to ask the question I've asked. And I agree that the implied question was along the lines of "As a feminist, should I disapprove of single-sex groups?"
Many of you have taken the time to explain why, in fact, I should not. You've put some very powerful arguments in favour of women-only groups, all of which I've read carefully and taken on board.
And I can tell you that between you all, you have convinced me that, as a feminist, I should be positively in favour of women-only groups.
Thank you.
I'm not entirely sure what the trans issue is as I haven't really researched it. I know one PP suggested I should have done, but the rest of you have proved me right in thinking you could explain these issues to me more clearly.
For the record I was born female and identify as straight female. I don't think about gender issues much, tbh. Most of the people I know are straight males or females. Or, if they're not, I don't know it. I don't (knowingly) see many trans people but have met a couple of them. I don't have a problem in socially accepting men who want to live as women, or vice versa. I can see that former men might as 'women' continue to behave in dominant ways, but I've never been in a group which didn't have one or two dominant personalities, not always male. Isn't the point of transitioning that they don't feel they ARE male and want to behave like women (if one can generalise about the sexes)?
I can see that there are some reasons (eg sports) why bio males shouldn't be regarded as female. And I don't regard men with penises as anything other than men - transvestites if they dress as women. If they've had the chop I'd be more accepting of them as women. But if they look female and behave female, why is it such a big deal? Would be interested to hear more for clarification.
