>You can't acknowledge they are male.

I feel that you're entitled to your opinion that transwomen are men but why shouldn't you be subject to the opinion of other people? If Reddit decides it's not the sort of content they want to allow on their site then I see nothing wrong with them removing it. You're free to register transwomen-are-men.com or get-the-blm-facts.com where you can discuss your beliefs to your heart's content with others who share your opinion. Finally I would point out that "womaness" is a mental and social construct so I'm not sure what facts there are to quibble about. If people were claiming that transwomen are of the female sex then that is obviously factually incorrect.
