First D&D is Satanic. Then it's Antisocial. Now it's Racist.
Best summary I can give. Some players maybe racists but the Author of the article is just picking on D&D to get notice.Any summary? I don't really want to make the time to listen to it, but I am curious.
Are there a few sentences here and there in the books that could be interpreted as racist? Sure. Is the game overall racist? I don't think so, no more than any other mass entertainment. It's virtually impossible for something like D&D to not have small bits and pieces that can be cherry picked to make a case for anything you want.
People see legitimate issues in the culture at large, D&D is a big target, I think many of the issues are projection. Doesn't mean we should not try to be aware of the issues, but D&D is just a ruleset.
