Opposing hate is an extremely laudable goal (even though genuinely well-intentioned people can reasonably disagree with defining hateful conduct and figuring out what's a proper response to hate) but I agree with your opinion. To me, this organization's activity looks to be a fairly thin veneer of "anti-hate" over a thick layer of ideologically driven political activism. To me, their focus on things like "Anti-vaxx misinformation" and "climate change misinformation" is bizarre if they were really genuine in their stated purpose.
Again that's not evidence. Does anyone know of any verifiable factual evidence this is true or even possibly true? I literally can't find anything so far. This isn't reddit people. This is HN. You need to back up your claims here. We're professionals.
