I can't believe the amount of people on these threads who don't understand this issue. It surprises me every time. There seem to be lots of people patting themselves on the back, thinking about what a lovely, inclusive person they are, blindly walking into a situation where the rights of girls and women are eroded in favour of men.
Sex is a fact. You are born with a vagina and are a woman - backed up by science. Gender is an idea. It's the way society thinks women do or should behave, backed up by stereotypes and tradition. I don't fit into this stereotype, and nor do most women I know. I don't wear much makeup, I don't like pink, I don't paint my nails, I don't wear dresses... I don't need to fit that stereotype because I am a woman. I just am. I don't need the offensive term 'cis' applied to me, because there is already a term to describe me. It's 'woman' or 'female'. I don't 'feel' like a woman, I just am one. Is there any way of feeling like a woman without resorting to offensive stereotypes and trivialising women?
I don't have daughters. I only have sons and a husband. I am worried about these things for myself. I see people talking about the fact that girl guides segregate based on sex being a problem, and highlighting the fact that there are differences between boys and girls, concluding that they should already accept boys because there is no difference. It's jumping the gun. If our society were already entirely equal, there would be no need for this separation. Our society is not equal, so it is needed as we work towards that.
A lot of people also seem to mistakenly believe that only trans women who are 'transitioned' would be allowed these rights. This is not true. This is discussing self identification, where anybody can decide they feel like a woman so must be treated as one, allowed into your private spaces and you are wrong if you are unhappy with this. You are being told to ignore your instincts, which are so, so important for girls (as they are socialised to please people) and risk your own safety.
Every time this issue crops up I am reminded of two things. Like many women, I have been sexually assaulted many times throughout my life so far. A man tried to rape me in a nightclub. I was very drunk, he came out of nowhere and grabbed me, tried to get his hand inside my knickers and shoved his tongue into my mouth. I was initially confused and thought he must have mistaken me for somebody else, until I tried to take a step back and he told me he wasn't letting me go until he had fucked me. I shouted and screamed and pushed and twisted my arms round and round but it was so loud and crowded that nobody noticed or heard me. He was dragging me away somewhere and I finally managed to twist my arms free, and ran as well as I could through the crowd, but he was chasing me. The only thing that stopped him was when I finally got to the women's toilets - the one place he couldn't go without it being noticed. My arms were covered in bruises. Imagine if men were allowed in women's toilets and women had been told that they were not to question that, because they may feel that they are a woman, so have a right to come into secluded spaces where they are vulnerable. It makes me feel sick.
The other thing I'm reminded of is a boy I went to high school with. He was a sex offender in training. Funnily enough, I can remember him standing outside the girls changing rooms telling our p.e. teacher that he was in fact biologically a girl and they couldn't force him to prove he wasn't, so he should be allowed in. It was always played down, eyes rolled. He used to draw violent, humiliating rape porn in cartoon style and leave it on our chairs. We sometimes had to go and play badminton at a place close to our school and walk there in our p.e. Kits. Girls had to wear a skirt. For some reason, we got there once and the place was closed. Our teacher asked that we put our trousers back on and he immediately placed himself in front of me so he could watch. Directly asking him not to do that didn't deter him - he felt no shame about his behaviour. The idea that he was humiliating me and there was nothing I could do about it was what he enjoyed. He wouldn't have seen anything anyway, he just enjoyed making me feel humiliated and vulnerable. It is people like him who will abuse this idea. There is no doubt in my mind that he would have claimed he 'self identified as a woman' to further his harassment of women. I'm not so naive as to assume that there aren't plenty of twisted people out there who will abuse this, given the chance.
I believe that transmen and transwomen must be desperately unhappy and I really feel for them. It doesn't mean that they are magically transformed into a person of the opposite sex and that women's safety and dignity should be pushed aside to make way for them.
