I didn't know labelling Randi Harper a harasser was a gamergate tactic. I know almost nothing about this whole gamergate business. I just visited the OAPI's site and recognized the name Randi Harper from my acquaintance's experience. He had a very rough time because of her emails, Facebook messages, and tweets. For that reason and that reason alone, I voiced my concern. I don't have any other motive.
Digging deeper, I see that Harper herself has been on the receiving end of some outright egregious behavior. I can only express my condolences for her and condemnation for her attackers.
Still, it seems to me that her organization will likely cause more harm than good in curbing online abuse. One can feel sympathy for another human being while also doubting their fit for a position.
But honestly, this whole topic is radioactive. No matter one's opinion or how delicately it is put, it gets misconstrued and pigeonholed. It's impossible to have an honest, nuanced conversation.
