Firstly, it wasn't tear gas, but pepper balls, and pepper balls are not banned, I think. But don't take my word on that.
Secondly, where have I ever said authoritarianism in itself is bad? I have never been unconditionally supportive of any type of government, democracy or other. I side with order and truth and I have no problem that the forces of order and truth crash down hard the forces of chaos and the lie.
I feel exactly the same way. But if you wanna know who God and the Devil are, you know where to go!
