I am not gay.  Or lesbian.  To be clear.

My belief is a large portion of your sexual orientation is biological as there have been studies showing that one's response to human sex pheromenes is in line with one's stated orientation.  Since you can not control your response to sex pheromenes,  I think it is probably next to impossible to change your sexual orientation.

Can attempting to change one's sexual orientation be dangerous?  The American Psychological Association believes so. 

As for the Baptists forcing their religion into law, of course they are. 

OK, lots to say here.

First off, I think that it is harmful to define certain sexual activities as bad more or less in general. I don't at this point care where that comes from be it religious, secular or whatever.
However, that is in general. Really, leviticus does include a general prohibition against incest and I can see some validity there. Then too, it also condemns lobster, which I happen to love.

Past that, the linked article goes in a direction that I really wish theists would not do. Sure, if quoting leviticus make you feel good, that much is fine but if you are going to use the bible then please read the bible. The article specifically uses romans 1 24:27 as if it was a general prohibition against homosexuality. Let's clear that one up with a bit more from the same chapter. The context is all important.

18For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;

 19Because that which may be known of God is manifest in them; for God hath shewed it unto them.

 20For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:

 21Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.

 22Professing themselves to be wise, they became fools,

 23And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.

 24Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:

 25Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.

 26For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:

 27And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.

 28And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;

Indeed, the passage does not say that gay is bad, it says that for other sins not specified, god punished whoever these people were by making them gay. Presumably, it would not be much of a punishment if they were made fully gay. Rather, in order to have punishment value, they have to still want “normal” sex but just not be able to do it.

Pretty much what is going on here is god saying “well, from now on, you will never sport wood again unless it is with another dude”. This is something that god did to them, not something that they were doing on their own.
