Legend
No, colonialism doesn't have to have all that to be colonialism. It's worth remembering that there were plenty of people who were only here for the treasure; sticking around was just necessary to get to it. Trying to obscure it by saying you need to hit all the ticks on a checklist is just trying to ignore the obvious.
But people have gone looking for treasure throughout history, myth and legend without colonialism too. May point is D&D doesn't actually feature anything that genuinely resembles real colonialism.
My sense is that most people understand the nature of this and get uncomfortable when it is pointed out, and thus get incredibly defensive when it gets brought up. I think the reality is pretty clear, it's more that you don't want to recognize it because you feel it says something about you
This is extremely simplistic. Now you are just projecting what you think people are feeling. I don't feel uncomfortable when people point this out, I just feel it is not particularly accurate. And I find it troubling that good aspects of a game are potentially being removed or avoided because people have been able to make this connection. But I don't think people are having a discomfort due to a twinge of conscience over your observation (I would say that response is rather cartoonish actually). Perhaps some people who are genuinely persuaded by your position feel that way. But I think people who disagree with it, just find it annoying more than anything else to have to defend dungeon crawling and exploring and killing monsters as someone perpetuating the evils of colonialism or in some way being infected with its residue
