Freedom of religion means you can believe anything you want and people have to treat it seriously. But there’s a limit to that, right? At a certain point somebody’s going to say, “No, that HAS to be bullshit.” Discordians gleefully hop that fence and run naked into the wild. It’s a blast, you should try it.
Seriously, if religious freedom protects your the right to, say, oppress homosexuals, it can probably be used for some awesome things too. Awesome things nobody’s thought of yet.
