If someone tells you to live up to a standard that they themselves do not live up to; they are an asshole and their opinion should be disregarded.

If someone tells you a standard of which they do actively live up to; only then are they qualified to discuss the benefits and costs involved. Then make up your own damn mind if you think it is reasonable for you.

So by default, any man who didn’t transition from being a woman, gets zero say in what I or you as a woman should do with our bodies or our lives.

(To be fair, it goes both ways)
