Here’s the thing unless you reject overwhelming scientific evidence you are left with the fact that 1) people do not choose to be gay 2) it would cause great harm to people to even attempt to change this fact about them and it wiill not work in any event 3) no one is harmed by others engaging in loving same sex relationships. ( The gay marriage cases detailed this science )
Reliance on religion to reject gay people has a problem here because unlike with much of belief which cannot be proved or disproved ( I cannot disprove the existence of a supreme being or that at some point that being has or can perform actions that appear impossible) there are incontrovertible facts in play here that makes arguments about “ two sides” and belief fatally flawed.
Once you accept the science, labeling gay people as doing something “ wrong” is, well in my book, morally wrong.
