This isn't a study, it's an event lead by 3 doctors. I really hope it's a positive event, I'm probably being overly cynical based on pervious experience with The Help Group.
I haven't personally seen that research, but if that's all this event is then great!
I agree with the statement that it's not a mental illness, but I wouldn't call it a choice. Being gay/bi is not a choice.
No, my implication is that new outlets/trolls/terrible people like to cherry-pick and will say being LGBT = being autistic. I worked with adults with developmental disabilities for 5 years and my wife's younger and older brothers both are on the spectrum so I'm really protective of the group as a whole.
What even is an Illness though, there are traits, then there are traits we cant control, then some percentage of those are illnesses
