Sexual orientation is not a choice.
According to many people it is lol
Being trans/non-binary may be, unless it's the thing we are not allowed to mention on MN.
Nobody wakes up and decide to be trans, who would ever choose to have a life of presecution that can end with them being beaten or even murdered at some point?
People who think someone "chooses" to be trans for attention literally don't understand how being trans is, because vast majority of trans don't want attention to themselves, they get attention because majority goes through transition late in life and inevitably can't pass as the opposite sex most of the time, which gives them a life of persecution, humilation, and suffering.
People don't choose to be trans because it's somehow "fun" or "trendy", they're like that due to gender dysphoria and some other things.
Just like with gays many in the past tried to "cure" them and make them live as their birth sex, didn't work just like it didn't work with curing gays, so the approach was changed
Trouble is, if you can ID as non-binary, there must be a binary to be 'non'. So sex is binary, yes?
Sex is binary, gender isn't, been many years that more and more people who work with biology, psychology and so on push the concept that sex and gender are two separate things.
There's literally studies about it, the idea of gender being separate from sex isn't even new, it existed for decades now, only thing that happened is that understanding of it advanced and changed.
