NEWSFLASH: I can wear any color or any shape of fabric and it will do NOTHING to change my gender identity or sexual orientation.
In a patriarchal society, it is perfectly okay for women to wear “male” clothing or “male” colors, because it is acceptable to BE MALE. But it is despised for men to wear “female” clothing or “female” colors because it is despised to BE FEMALE.
Bullying a child for liking particular colors or clothes is not acceptable. Rejecting a child who likes the WHOLE spectrum of colors instead of just those colors that society has randomly assigned to correlate to having either a penis or a vagina is not acceptable. Assuming that a boy liking pink or a girl liking blue has anything to do with their sexual orientation or gender identity is not acceptable.
