Ra-men.
Xtian presidents and politicians may have helped to protect the rights of LGBTQ citizens. However, it is those who have used religion as a bludgeon who have created the need for that protection. Ditto for slavery, for racism, for the hate crimes against non-whites, the indigenous, Jews, even (to a much lesser degree due to our low numbers) pagans and other non-Christians in this country.
Unfortunately it is also the religious who have tried to prevent some aspects of scientific research like stem cell research, vaccines, IVF, teaching basic science w/o injecting creationism into it, gene editing and cloning, etc.
Until we can weed that out, less religion in America IMO would be better.
