I mean it's all bs but Paul says that it's unnatural for men to have long hair so... I don't think Pauline Christianity would have been very trans-inclusive
That's not something that stuck with me, probably because I'm a woman, and those things aren't that important to me. A quick search says the Torah says not to let the hair grow wild but to trim it. I'd have to dig deeper, into the Jewish learning sites. Thanks for this!
