Many years ago, I read an article in a science magazine, that said some molecules in the air, apparently of industrial origin, might have an effect similar to sexual hormones, but nobody had any idea what it might eventually cause. I think the appearance of trans people nowadays might be a result of those molecules. Interestingly enough, I've almost never heard about it since. Apparently the industries that might be responsible for those molecules are lobbying to keep it quiet.
Trans women are not choosing to invade your space. They've been put in your space by environmental malpractice that's almost certainly the result of cis men's irresponsibility. Those industries have a vested interest in preventing you from joining with them in solidarity.
