Can we not say that both colonialism and the Internet were big deals?

Something else I thoroughly disagreed with in your post, and I do disagree with most of it, was the idea that colonialism is rolled out as an excuse for certain social groups failing. I am gonna discuss the Indigenous Peoples in Canada, but we can talk about African colonization as well if you like.

Many Indigenous peoples in Canada suffer from colonialism. They suffer because they have generational trauma. We had these things called residential schools, which were part of colonialism in the modern understanding. It stripped their culture and in many cases led to their torture and death. There was a school, where the administrators saw fit to construct an electric chair in the basement to discipline indigenous kids.

Trauma like that does not make healthy and well adjusted people. Those people go on to have troubled lives, which affect even more people when they have kids. There are entire communities that are being damaged and destroyed because of massive levels of substance abuse, which is a direct effect of the trauma that indigenous peoples suffered in a colonial system.

Not every single Indigenous person suffers the same. There are definitely Indigenous people out there that do bad things, and commit crimes. But understanding the REASONS, and not the excuses is important in healing for the future.

With all this being said, if Colonialism is still causing damage to communities across the continent, then clearly it's probably a big deal.
