In this context, he is supposed to be an opponent of GG.

Many of Gamergate's opponents are ones who are insistent on tolerance and diversity in everything, and take it to an extreme (they're sometimes called SJWs, although that term gets horribly overrused).

This comic is saying they're not 'improving' society by enforcing their social justice on people, they're only making it worse for people who they do it to.

Maybe worry more about telling a good story or providing good gameplay and worry less about who it might offend or meeting some ill defined minority inclusion quota.
