IceBeing, you are being worse than ridiculous. I do of course know their sex. They are either boys or girls, and how they express that is up to them, be it in leaning towards sports or art or music or cooking or fashion. Some are outgoing, some are reserved, some are kind and empathetic and some are more brash. If you asked them they would tell you whether they are boys or girls, because they have a solid grasp of very basic biology and understand how to distinguish male from female in the human species. It's not that hard. You can wear pink shorts and play the clarinet and enjoy creating nice desserts for your family and keep your bedroom neat and pee in a urinal in school, using your penis.
And it is not in fact a local problem. Though it may of course be a local problem in multiple possible different places across the world (lol)
With that remark and your insistence that sex is irrelevant and unknowable and altogether mysterious, I am wondering if you suffer much from back pain, since twisting yourself into a pretzel seems to be a habit of yours.
Thirdly discrimination by skin colour is also perfectly natural. We feel more relaxed and secure around people who look like us. Totally natural evolutionary bias.
You are speaking for yourself and only yourself on that score. You should be utterly ashamed of yourself.
Race is a hierarchical concept based on the artificial concept of race. Its only function is to maintain the oppression of those 'races' considered inferior. Our culture is awash in racism and has been for centuries, but that doesn't mean it is anything but an artificial construct. Or natural evolutionary anything. Same goes for gender. Shame on you as a woman for seeking to carve in stone something that has only done women harm. And if you are a man then educate yourself.
The only reason kids don't think it is okay to only have white friends is if we show by example that it isn't.
And of course you have got that bass ackwards too. Children learn racism from their parents. They don't unlearn it from enlightened adults. There is no 'natural evolutionary bias'.
I am gobsmacked.
I am actually speechless.
