It *would* scare them if they thought it was a real possibility. Similarly, the Second Coming of Jesus Christ a *very scary thought* to basically everyone, but very many people are confident it’ll never happen. So they aren’t really worried about it. I think it’d be pretty cool if we got a White American Genghis Khan. There are lots of guns here, and many rural Whites own large tracts of land where we could conceivably form war camps. I bet that thought scares them, too.
