That's incorrect. Free speech is seen as a right because good ideas need to be heard.
Not just good ideas, but just as important is the right to point out when bad things are being done by people in authority or power.
The Ontario Liberals proudly tell everyone who will listen that they've balanced the budget.
I have the right to call them a bunch of
**** liars and point out they're borrowing over 20 billion this year, and will borrow over 30 billion next year. Without freedom of speech I might be locked up for saying that. God knows this is a party with zero respect for anything but raw power. I'm pretty sure if they could put their political enemies and those who criticize them in labour camps they'd do it in a second.
