It's not a race issue; it's a class issue. The non-white people that SV companies employ tend not to be the underprivileged people that are driven out of metropolitan areas due to gentrification.
Bomb (or brick) throwing is trivially easy and makes the thrower feel like a badass without actually helping anyone. Actually trying to look at all sides of a complicated issue, figuring out what should be done about it, and trying to make a difference is hard, thankless, and humbling. It will make you feel stupid and inadequate for the task, because it's hard and it's worth doing. People who care about those things don't have your comment history; people who are feeding intellectual conceits do.
