The issues is "Should adults have the right to enter into contracts with a school that requests certain conduct in line with the social standards of the school?" The rule is universal with one exception. Anyone is free to agree or leave. I say yes. I am gay, but the actions of the LGBT justice warriors are an attack on free choice, as they try to force their own biased choice on others. Would they go after Muslim Islamic schools that actually teach homosexuals should be killed because they offend Allah (as happened in Orlando)? No certainly not. That would be called Islamophobic, even by the LGBT community.  Christians, though, are easy targets. This enters the realm of persecution rather than equal rights.
