Many of the issues CAN and are linked to colonialism, reread what I wrote.
Yes, your points are pertinent and support problems that colonialism is relevant to, I did not claim otherwise.
However, you’re clearly angry over crimes (in many cases rightfully so) and problems the US has caused. But the question wasn’t exclusive to the US and is not exclusive to the US.
For the OPs question, trying to exclusively link everything to or overstate the colonial influence is an example of what I was saying as well.
It’s comforting to pretend that we just say one word “colonialism” and think that now we’re experts on the subject. But there’s so much more than colonialism, which again is a big factor (the first I listed), and overemphasis of it while disregarding the other real issues and nuances is counterproductive to learning.
