I believe you. And I would never try to invalidate your experience.
But there's a difference between the experience of any individual man or woman with ME, which is one kind of discussion, and the overall statistics for men vs. women (and nonbinary? gender fluid? - I don't want to leave anyone out).
I think it's important to separate the discussion of a systemic issue (like sexism or racism) from the discussion of what happens to us as individuals (doctors often treat ME patients badly, period). These topics are related but they are different topics.
I'm sure there are men with ME out there who have been treated worse than I, a woman patient. No question!
But I'm pretty sure there certain types of comments that I get which are different from the comments that men get.
For example, early in my illness, before any diagnosis, I had an appointment with a new doctor. After telling her my symptoms she saw my recent tubal ligation in my chart. Then she asked me whether maybe I was feeling regret over my choice not to have children.
It's hard to imagine a doctor asking a man whether symptoms like dizziness, nausea, feeling short of breath, exhaustion, etc, could be caused by his regret over a recent vasectomy.
