I only think of people who pretending to be the opposite sex a tiny amount of my day. I don't think people can change sex, because I believe science tells us it's not possible. I'm with Lord Winston on this subject.
I am not a cis woman. This is a divisive term, and I'm for women's equality. At the same time I believe men and women are entitled to their own spaces. People who don't want to live in the sex they were born with should be offered a third space, similar to a disabled bathroom, so that they may not mix with their adopted "gender". I am a woman. Only a woman, that's it.
I think men and women can dress how they please, wear makeup, have whatever hairstyle they like, to express themselves. Wearing an item of clothing doesn't denote what "gender" they are "feeling".
I don't think I'm "transphobic" because to have a -phobia I must be scared of transgender people. I am not at all scared. If I am to criticise some people demanding to take over single-sex spaces or for everyone to use pronouns in their email signatures then I might be accused of being anti-trans. I think that is more of an accurate term than transphobia.
Everyone is entitled to feel safe, regardless. I think everyone has skin in the game on this debate. I think safeguarding should be everyone's first priority. So if that means separating groups for that to happen, so be it.
