It doesn't matter if some of them keep to themselves. What matters is that those communities continuously spill out and if that has detrimental effects. I contend that they do and they have.

The combination of these two things lead to things like gamergate and "doing it for the lulz" and ends with things like the march in Charlottesville and the El Paso shooting.
