What's the Internet rule about people bringing up Nazis and hitler?
Godwin's law.
Also, getting into the religion industry is as easy as registering to be ordained online. Have fun.
In regards to the overarching topic, discrimination versus free market choice is a very difficult topic to cover due to spatial and other economic factors. I don't support the discrimination of anyone based on the merits of race, gender, sexual orientation or religion. However, I do support the refusal of service to those groups that advocate harm to other human beings. Legally writing this definition seems to be difficult, I will leave that to the professionals
