Something I worry about: is how any position that is not extreme will get invariably get “primaried” by those with more extreme positions in any online debate. 

They will attract more energy , easier to get social capital and also plays well to most online algorithms. 

Having the center get and hold energy seems an unsolved problem.

Certain people have also made use of the hate watch, because the algorithm doesn’t necessarily care if someone is just there to point out something is false, it’s engagement either way which means promotion.
