The current and past ideas and language surrounding orcs, tieflings, and a bunch of other sapient beings is problematic in D&D and other RPGs. If your response to that is, "They're fantasy," my response is, "It should be no problem changing it for safety and comfort of players."

This isn't to say there aren't evil orcs. There are. Just like there are evil humans! Monolithic thinking like this is bad and boring. There is a lot of racism baked into our fantasy. It's good to call it out and change it.

When we do that, we get games that are more fun for everyone and more creative and original. I want good beholders and mind flayers and evil angels. I want language that wasn't used to describe existing humans to make them seem lesser than others.

And I am 100% still learning this. Listening to others is huge. Doing research is important. Hiring and working with people who are not exactly like me is the best thing that can be done. I learn new lessons everyday and have my eyes opened. Thank you to those who speak up.
