Sure, one or two people putting their baby in the microwave is the same as Christians killing and torturing countless Jews and Muslims for not being Christian. Totally justifiable comparison.
I'm not surprised a Christian like you would try to excuse all the murder that way though.
As far as Christianity is concerned, gay people are living in sin. And as long as they are not repenting or seeking help with their condition, they cannot be saved.
I mean come on, at some point you gotta look at this whole thing reasonably. Where has all the LGBT acceptance in the West gotten us? There's gay people in the White House, transgenders in the military, pride parades in every major city, and yet somehow we're still arguing about whether gay people are oppressed because some states won't allow them to teach children about anal sex.
At some point you have to ask the question whether gay people are living in a state of feeling permanently oppressed not because of what Christians will or will not allow them to do, but as a result of their sinful lifestyle?
FWIW, I'm not sure that putting them in prison is the right way to deal with the problem, but from a Christian perspective, there isn't much anyone can do about it as long as they insist that being gay isn't the problem, lack of tolerance is.
