I haven't touched any GamerGater content creators but I'm trying my best to flood my recommended with some more non-white let's players.
I watch Markiplier, and Cory. And I have some POC Vtubers but I want to try and find some others that I can show other people.
I like Woolieversus on youtube and Arcard on twitch (he mostly does RPG/Strategy games) both are POC. I also like heyitscara she is a lesbian and plays mostly paradox grandstrategy games such as Crusader Kings 3. I know there are more but these are some of the ones I follow.
Woolie is cool. I miss Superbestfriends though. Those guys had a really good dynamic together
