Never said Westerners were the only imperialists. But the scale of their foreign interference, in recent times, is unmatched. The Japanese mostly stayed within East Asia.

You can attempt to throw out as many supposed counter-examples you like. Nothing will match the scale of destruction and genocide that was the European colonial era.

No one is saying that the Europeans were the only ones that lacked the ethical framework to forego the colonial pursuit. The point is that they absolutely did lack that ethical framework and, well, here we are. There are many cultures on Earth that would not have done what they did, if given the same circumstances. Even though I know you'd prefer to focus on the cultures that would.

That doesn't mean white people are more evil or violent. I personally beleive Abrahamic religions are often interpreted by their followers as a justification for conquest. It's part of why Europe and the Middle East are so similar in their imperialistic aspirations over the past millennia.

Also you're not a sociopath. The argument that you suggested is sociopathic though.
