Many people share your viewpoint on the left and right. It's natural to support free speech for what you agree and censor what you don't. It's part of living in a left or right ghetto of thought.

Take a step back. The right is in power you are not allowed to speak your ideas. The left is in power you can say anything that supports their agenda.

What you can never do is speak against the government right or left

Why would you want that? Seems like the worst of all worlds.

Isn't the history you are trying to not repeat a history of controlled speech where the wrong party got elected or got in power? Why won't this happen again and again?
