Are you now arguing that homosexuals are born that way? You are all over the map here.<quoted text>The deaf or blind person may think it's natural for them as well, but that still makes their condition a handicap or a birth defect.
Being born blind or deaf is defective and not natural. It's not a slur against them, it's just a fact. A blind or deaf person is severely limited to experience life fully.
Why would your "designer" allow handicaps? Isn't that subverting the free will of one who chooses to see?
