Not everyone agrees that people must refer to all males in real life, as he. You'd lose friends in a heartbeat. It's not personal. It's not about individuals.
There are, indeed, many women who simply refuse to do so, and are quite happy to shed friends as a result. But there are equally, others who don't.
Personally, judgment in that context has to be tempered by understanding. But that's not the same as disagreement.
I genuinely believe that if you call a single man, she, you are contributing to the problem. (And, of course, I understand one doesn't want to be hurtful to friends. The two things aren't mutually exclusive).
Transgenderism as a concept is profoundly sexist. The idea that a man could adopt the accoutrements of 'womanhood', in order to 'be a woman' relies on sexist stereotyping.
You don't get a man claiming he's a woman, because he's the CEO of a company, do you?
So if it relies on sexist stereotyping, which has historically been very detrimental to women, why would one help to perpetuate it?
Especially for the sake of 'being kind' to the very cohort who is doing the oppressing!
Hint, I don't believe any of this is about kindness, it's about power. Because if it was about the concept of kindest, how come it only ever goes one way? And women are always the losers...
