I would suggest that part of the reason is that it comes across as you having an axe to grind, rather than what you’re saying. The conversation was one party agreeing with you about there not being great treatment options until recently when studies have finally been conpleted with you saying, ‘you’re wrong, my experience proves it, anything you say is an attempt to invalidate my experience’

That is quite probably not at all what you intended but that is how I interpreted that exchange.
