Girls, Gay is ok, but medical condition is not?

I have a medical condition.

Because of that, I cannot tolerate cosmetics and man-made smells.

So this is the question :

Why, do people accept that soke people are homosexual,

But don't care accept someone who can't be around smells and cosmetics? And treat him like an Alien.
