You raise a lot of interesting questions, like: why do hexbears have shirtless photos of Hasan but not shirtless photos of Asmongold? Why isn't the slop comm a shirtless photo of Asmongold?
Also you assert that Hexbear doesn't receive new users because hexbears are supportive of Hasan. Why then is Hasan's community so much larger than Hexbear? Hexbear was created at the same time that Hasan started streaming and the communities were the same size. Now Hasan millions of fans, some who say he inspired them to engage in activism, and Hexbear still seems smaller than when it was a subreddit. It must be Hasan that is holding back Hexbear's growth? Could it be that Hasan made his community have focus on optimism while communities like /c/slop are built on pessimism?
You don't have to like Hasan. There are even many people in Hasan's community who criticize him. I said that it hurts the website to say that everything that you don't like should be posted into the slop comm. I think it's totally fine that you don't like Hasan. My point is that comms other than /c/slop are allowed to have posts that you don't like.
