Why is there a trend these days of denying biological sex?

It seems like trans activists ( not just ordinary trans people) are telling women to shut up about their concerns over biological females rights in for example professional sports. It seems anyone who agrees sex is a biological reality is now a trans exclusionary radical feminist and trans activists hate radical feminists and feminists in general. These autogynephilic males are deluded and narcissistic. And they hate women who speak up and call for violence against them. I mean also intersex rights and trans rights movement's are seen as one and the sane and they aren’t. It’s a crazy rabbit hole. They went after author J.K. Rowling for instance. I feel like though we still have a long way to go for lgbtqia acceptance but trans activists are ruining everything. There was even talk about the lgb without the t which puts transsexuals in a predicament. Trans activists even bully transsexuals who don’t agree with them. The trans activists are dangerous. I would not want to encounter one but where I live that’s not likely.
