Freedom of Religion MUST include the idea that religious groups have the right to limit members to those who agree with their views. Otherwise it is not freedom. Atheists could join in sufficient numbers and vote to make the group atheist!
This doesn't just apply to religion but to every organization. Gay groups should have the right to limit membership to gay's only. Democrat groups should have the right to limit membership to Democrats only. Atheist groups should have the right to limit membership to atheists. As seen in this article, anti-discrimination rules and laws are being used to destroy freedom and even to trump the Constitution.
Granted, some discrimination is evil--like discrimination against people because of their skin color. But the freedom of discriminate on the basis of viewpoint is essential to freedom, both Freedom of Religion and Freedom of Speech.
Frankly, I think someone needs to make this point.For example, non-gays should join a gay organization in overwhelming numbers and then use their majority to vote to shut down the group. That would probably put an end to this nonsense immediately.
