These being statements by Pat Robertson pretty much means that they are full of factual inaccuracies.
#1 It has been shown that reparative "therapy," which he is tacitly advocating (gotta read between the lines folks), has an adverse on people's mental/emotional well-being. On the other hand, I'm reminded of a story where two men met at one of these reparative "therapy" places and ended up getting married, so maybe they aren't 100% bad (just 99.99999% bad).
#2 There are no reputable studies that show that reparative "therapy" actually works. Quite the contrary actually.
#3 While science has not come to a conclusion as to what causes/influences sexual orientation, the science that we have thus far points demonstrably towards biological factors (primarily during pregnancy). In others words, it isn't a choice. It isn't acquired and thus cannot be "unacquired." What exactly is he basing his (false) opinion that homosexuality is acquired on? One word: IGNORANCE.
I have said it before and I'll say it again: why do people listen to RWNJ's like Robertson? I guess that's a mystery God is keeping to himself.
