Actually, you’re just reducing complex issue of exercising power over other countries to “colonialism” than trying to criticize people correctly recognizing this issue as “radicals”. Most of what you listed can be directly linked to western countries destabilizing other regions by military or covert actions, installing puppet governments, using their influence to steal resources and keeping other economies in check so that they don’t develop into competitors. No one thinks that it’s all because some country was a colony 200 years ago. Western influence never really ended in most of those countries and that’s what is keeping them down.
