Three examples of the top of my head where I think it leads to problems.
1. Caitlynn Jenner winning "woman of the year" after being a woman for about 5 minutes. Really? Cant find a better woman in the world than some f**ken idiot that was born a man?
2. Trans men playing women's sports. Disgraceful and shouldnt be allowed. I feel sorry for women who have to put up with that shit.
3. Public bathrooms. If gender doesnt mean anything anymore does that mean any old f**ken pervy bloke who thinks he's a woman can use the ladies shitters? They are already vulnerable enough FFS. Why cant they have a safe space free from biological men?
Anyone supporting this gender nonsense is just a woman hater.
1. Sure they could have found a biologically-born woman for the award. But maybe the award isn't about biology, so why shouldn't they consider someone who has travelled the journey of aligning their outward biological sex to their inner concept of gender. (Not a huge fan of Jenner, but don't think her winning the award was a big deal or problem.)
2. Agree with you there, a lot to still work out within the confines of the historical two-gendered model of sports in the modern world.
3. Loads of places I go, including kids playgrounds when mine were growing up, have unisex toilets. Also seen lots of unisex toilets in shopping centres. This in a sense promotes safety because everyone gets their own cubicle, and there's no excuse for loitering anywhere and claiming anything in terms of gender. I think the world's moving away from two-gendered division in these spaces, and there hasn't been much of an outcry.
