This man should be heard. Free speech gives him the full right to spread his vile messages. If we couldn’t hear him, we wouldn’t have the opportunity to oppose him.
What he really is after is not just the right to state his views. He wants his religious rules stated into criminal and civil law. Exactly like pretty much every single Christian. It’s the number one rule of organized religion: don’t be content with praying to God in your own privacy at home. Organize to get power in society, to force your rules upon everyone else, to give yourself more privileges, and to deny others their human rights.
When the religious gets power, free speech is the first right they remove from others.
