When I was a kid, I was a girl and me and my best friend (also a girl) went to Dungeons and Dragons games hosted by a DM at a local gaming shop. We were in middle school, the other players and the DMs were all adults.

There was a guy who would regularly teasingly poke my friend in a way that was clearly inappropriate and uncomfortable. Nobody stopped him. We did go for a few more sessions but eventually stopped attending. We stayed in the hobby, but it’s not a mystery why people would leave.

Not to mention the underlying currents of racism in a lot of games.

I know D&D and homebrew aren’t the same thing, but D&D is the intro for a lot of people so it’s very relevant.
