Colonization!

Psychological effects of colonization still present? Thats what the article I read is called. I didn't know that there were psychological effects of this. Well in the article it talks about how colonization has been one of the worst things ever. I guess it has been bad, like how colonies started slave trade and that unequal stuff. But without colonization half the countries and stuff we have today would not be here. I suppose there is effects that really change how people are today. If there exprience was bad they still probably have post problems. I guess this whole idea could go either way. Personally I don't care about colonization, I'm going to be honest.
