I would not disagree, but wouldn't that follow the demographics of the population to a big extent? If we examine other communities in other languages, what were their dispositions, who did they target or not target? Did blondes target blondes or non-blondes, etc.
In other words did it or does it show disproportionality? If it's disproportional then that indicates it's outside the global norm. The above does not mean the global norm is an acceptable norm but helps calibrate and figure out how good or bad things were or are.
How is that relevant? Yes communities tend to be prejudiced against things outside their assumed norm and the anonymity of the web makes it easy for them to express it without repercussion. That doesn't make the negative impact it had on people in those communities not real.
Furthermore in regards to race specifically I would argue there probably were very few online tech/engineer communities anywhere in the world that widely targeted and denigrated white people until maybe just recently, and even then they are likely not popular or widely participated in.
I'm struggling to understand what the point you and other commenters here are trying to make responding to the original comment.
