I am all for recognising that not all women are treated equally (assuming that I fall into the Some Women category to which you allude?) Where I part company with IF is that it brings men under the umbrella of 'women's issues' which, IMO, means that it is not a feminist movement but a humanist/egalitarian/socialist one (delete according to your ideological viewpoint), and male rights always trump women's ones, whether the males in question 'identify' as such or not.
But we've been here before, so let's not go down that diversionary route?
So you are at a meeting of intersectional women Doodledog. Say staging a protest on International Women's Day. There are a few people there who are "butch". Do you ask if they are men? Do you demand to see their genitals? Or do you behave like any normal person and accept them as women? If you do so are you then betraying feminism in some way? Because they may be transwomen.
What? Of course I don't ask if they are men! And to suggest that I would ask to see their genitals is ridiculous and insulting. I don't behave 'like' a normal person - I am a normal person, and wouldn't dream of doing anything of the kind.
I don't buy into gender woo, and would accept anyone as a person. I am not saying and have never said otherwise.
What I am saying is that men (or 'penis havers' if you prefer) should not be allowed into spaces reserved for women. Such spaces are only there for women who are ill, in a state of undress, or otherwise vulnerable, eg in hospital or prison where escape may be difficult. I appreciate that it is not always possible to be certain of someone's sex if they go out of their way to 'present as' the opposite one, but that's not the point. We have laws to protect the innocent from the ill-intentioned, and that means that some well-intentioned people get inconvenienced along the way. I couldn't invite myself into a neighbour's swimming pool if they had one, because it is their (hypothetical) space and not mine. I can't wander into a nursery or primary school uninvited, as I am not a parent of a young child. I wouldn't wander into a male changing room as I am a decent person (despite your implications above) and am aware that my presence might cause embarrassment. Or into the men's section of a synagogue or mosque. The list goes on. Respect for the boundaries of others is the mark of a 'normal person' and I like to acknowledge that as far as possible and treat people as I would like them to treat me.
Asking someone their sex and asking them to flash their genitals would outstep those boundaries by a country mile, as does saying you are a woman and entering a female space where women are undressed or otherwise vulnerable.
None of that is betraying feminism. Saying that men who dress as women should be able to access all areas (unless it can be proven on the spot that their presence might deter woman from attending) is absolutely betraying feminism, however. As is approving of allowing trainwomen to compete against women in sport, and to take women's places on all-female shortlists.
How laws are policed is not down to me (or any other member of the public) to worry about - we have a police force and a legislative system to do that.
