I agree, particularly with your point about thinking critically and treating others with dignity, but at the risk of sounding overly pessimistic, why are you hopeful that the broader tech community can help, or even wants to help, leapfrog all this ugliness? As a somewhat outsider looking in, most of what passes for the tech community from what I can observe seems primarily focused with tracking users so that these users can be targeted with advertising to "aid" them in future purchasing decisions. I'm not entirely sold on the idea that this is the community that's going to instill positive change.
