The world is better because people like me were alive, but thanks anyway.
Can you name one objectively bad outcome from colonisation? None at all? Didn't think so.
The worst you could possibly say is that in some cases the colonies eventually left leaving retards with fancy toys but none of the know-how so they imploded but that's the 100% worst you could say.>inb4 muh treatment
Who cares, people are treated poorly in literally every form of governance or system of economy. People are treated even worse than that without those things too. It's a moot point especially when quality of life rose dramatically.
Face it, there's literally no argument you could make against colonialism that is valid and not entirely based on emotional appeal (which as shown above can be generalised criticism to all systems and thus invalid)
