I never said that WotC should fight the ugliness in the world. It is those that search for racism and whatever else in the books that should stand up and fight the "ism" in the world and leave the hobby alone.
As I said, all my experiences with RPG have always been open, inclusive, fair and open minded with others. To me seeing real world "ism" in the books is a such a stretch on reality that it is an insult not only to those who like the games and have always played it with no "ism" present at their tables, but more so to those that really are victims of "ism" in the real world.
It is to these persons that I say:" If you really want to fight the unfairness in the world and the "ism", leave the hobby alone and go in the real world where the fight really is."
