This is a very worrying development. I don't know what these people on the Left actually think they're achieving. Do they seriously think skin colour motivates behaviour? That is what's generally known as racism.
If you want to simply ask why the majority of mass shooters seem to be white, fair enough. I assume it's probably something to do with a combination of being middle class and being part of a cultural group (in the US) who has an ideological attachment to guns. Obviously this sort of thing doesn't happen in Europe at all really. If it was somehow caused by skin colour, you'd have to predict it happened everywhere white people are.
And given the racial imbalances in homicides in the US (i.e blacks being massively overrepresented), you have to seriously wonder why this line of thinking is being pushed. It's almost like they're deliberately pushing for the Right to return with a race-based analysis as well.
