The reason it can be discounted is that being called names in online games is hardly something exclusive to minorities. If you go play League of Legends for a week it doesnt matter who you are, you will have been called nasty names by someone. If they know some aspect about you they will try to attack that, if they dont it will just be random insults hoping that something will stick.
This behavior is not fun or good or excusable, but it is not a problem steming from racism. Trashtalking is older than video games.
Also if your bad experience is with other people calling you names, that problem will not be solved by trying to shove sensetivity readers into the studio making the game, that random troll you play with online is still going to call both you and me names, trying to rile us up.
If you are really concerned about racist material available for purchase I suggest you focus on trying to get Amazon to pull mein kampf off their store. If the source of racism in society is what books and media people have acess to then surely mein kampf is a much bigger problem than some DnD game?
A few things here:
A) The insults people use online are not targeted. Plenty of gamers use the terms n***** and f** without knowing anything about the person they are insulting. I absolutely think this is bigoted behavior. Does that make the person a bigot? Not necessarily. It just makes them a jerk. They could actually be a racist or could not, but that is immaterial to the question of whether or not the gaming community is generally open and inviting.
B) The sensitivity training wasn’t my idea. That was the OP’s suggestion to deal with how Larian handles LGBTQ issues. That is a separate conversation from people using bigoted insults online.
C) I’m not concerned about racist material for purchase, and I’m not in favor of censorship, especially with important historical documents, but also in general.
