There is definetly a camp of developers (not outsiders) who have denigrated StrongLoops decision and praised LambdaConf. These are engineers who may work with members of groups targeted by this fascists' views, engineers who may review a Black / Latino applicant for a job, contribute to the overall work environment for them.
To my point, what I see is a co-optation of the meaning of the world tolerance. When there is an fascist antagonist on minority groups, it is easier for these "tolerant" everyday individuals to say hey fascists should matter too at tech conferences. Because thats what tolerant means, even the fascists and racists matter, no? Things that appear logically equivalent are not always the best things to do. Part of me thinks this is part of antebellum United States' original sin; the wealthy white class using race and slavery to spur hate-mongering from working-middle class whites, who saw Black people as their problem and not class inequity. This is the "vicious lie" that MLK talked about and continues to manifest today as Tim Wise deals with: www.timwise.org/2015/04/how-racism-explains-americas-class-divide-and-culture-of-economic-cruelty-an-excerpt-from-under-the-affluence/
