“I agree with French and would add that it is possible for non-religious people to think homosexuality is morally wrong.”
Whether or not an abnormality is tolerated by a society depends on whether that abnormality is generally perceived as harmful.
So arsonists who take great pleasure out of setting fires are not tolerated by societies, even if they are “born that way”. But someone born with abnormally poor vision is fully accepted by society.
Whether homosexuality is harmful to society is not quite as self evident. It may take decades for the effects to show up. The fact that the Bible treats it as a sin probably means that in the long run it’s not a good thing.
Arguments are made that one reason the Roman empire fell was because of it’s decadent debauchery.
Time will tell, but I think that societies with traditional sexual mores and family structures will fare better in the long run and may end up dominating those that choose otherwise
It did not take long after the beginning of normalization of homosexuality in the late 1960s and early 1970s for an AIDS epidemic to occur, killing hundreds of thousands. The homosexual movement now promotes genital mutilation AKA transgenderism. Meanwhile, fertility in the U.S. has been falling. The harmful effects are showing up quickly!
