I have an issue with authoritarianism (both left and right wing), and violence employed against political dissenters.

Revolution is violence against political dissenters and is authoritarian, considering that revolutionaries impose their will upon somebody else by usage of force.

But hey, everybody willing can explain why violence against fascists (who are the "political dissenters" in question) and authoritarianism (i.e. having a government and a military) are bad and shouldn't be done by the Global South.
