Normally individuals will choose to filter out the content that they hate. Since that content can't be forced through via an algorithm, the muting provides friction for the undesired content to spread. 

 don't we all love a bit of hate scrolling tho? or do you think that's algorithmically induced? 🙈☺️ 

 I think very few people naturally like seeing things they hate to stew in their negative emotions. The rest are the victims of targeted propaganda efforts to keep them in a state of fear and anger.
