@izzythepush,
You are making an argument
against free speech.
1. You are saying the government should have the power to
restrict hate speech because it will (allegedly) stop hate groups from attacking, abusing or killing people.
2. You are saying the government should have the power to
censor anti-vaxers because people are dying of diseases.
This is your opinion. I disagree with it. But if you are arguing that the government should have the ability to restrict speech and prevent opinions from being expressed... don't call that free speech (no matter how good you think the reasons are).
Every government from the UK, to Thailand, to North Korea allows citizens to freely express ideas and opinions that are deemed acceptable by the government. Calling this free speech is ridiculous. Once the government has the power to label certain ideas as unacceptable and punish people who express them... there is no longer freedom of speech.
