In psychology, they say that often times when someone a certain issue but has a difficult time dealing with it, they project those faults and problems onto others (it's called projection). In other words,Bryan Fischer doesn't need to be handling a radio show (that for some reason people listen to), HE. NEEDS. HELP!!!
Also, even if he said about gay people being mentally/emotionally stable were true, maybe that wouldn't be the case if we weren't subject to discrimination, demonization, and demagoging. He's would b pointing out the symptom (instability) but conveniently failing to mention that he and people who espouse that adamant ignorance are the real problem.
Of course, however, Bryan is full of crap.
