The joke is on me, I guess. I've never understood how the line is drawn. Freedom of speech and religion are both in amendment one. Free speech is a right, but one can, evidently, open a website and suppress any opinion one chooses. Freedom of religion is a right, but one cannot use religious beliefs to deny gay people their rights. [1] That seems like a double standard to me and I've yet to find a way to reconcile it.
Freedom of speech protects you from government prosecution, with certain limitations like yelling "Fire!" in a crowded theater, etc. It doesn't mean that others (e.g. Reddit) have to give you a platform for your speech.
Freedom of religion won't let you practice something that impinges upon the rights of others or violates a law.
