I wish I thought this were a good idea. Successful sites I have participated in started with being aimed at a particular diagnosis. I wish I thought this would work because it is clear to me that different diagnoses with symptoms in common often have related underlying causes. Unfortunately, this looks too nebulous to me. I hope I am wrong and I am routinely accused of erring in the opposite direction and making sites that are "too niche." But that's what it looks like to me.
PS Arguing with people who have given you feedback is not a great idea. It is a super common thing, but it really isn't a great idea.
