This is what the "left/alt-left/whatever you want to call them" don't understand.

You may initially benefit from censorship because you are the initiators and the one's with the pull, but sooner or later, everyone else will start organizing.

When mormons/christian groups/conservatives/etc organize and start flagging atheist/lgbt youtubers/content and getting them taken down, are you going to celebrate censorship?

The beauty of free speech is that as long as everyone has it, you have it too. The problem with censorship is if you can censor, then so can others.

Fine. You don't like hateful racist speech. Ban it. But others don't like hateful atheist/lgbt/etc speech either.

I'd rather live in a free speech world with "hate" than a censored world without "hate".
