Although it's carefully couched with "some criticism is useful", it's disappointing to see the idea perpetuated that offering disagreement and negative comments makes one a "hater". If I criticize something about your idea, I'm not doing it because I hate you--maybe I just think it's a bad idea. There's enough actual hate out there. Equating general negativity with hate downplays the seriousness of hate and does a disservice to actual victims of hate.
