Got into an argument with my MAGA mom during the holidays and at one point she said, "so, you think white people should feel guilty?!" Took a lot of will power to not say, "no, I think white people should die!"
Well said. I forgot that point that it was even more concrete than how I stated it. The strategy was to weaken the left. The tactic was to do that by stigmatizing communities associated with the left because of their association with weed.
That could be a factor, but there are politicians from back in the day recorded saying they stigmatized weed to counteract the politics of blacks, hippies, etc.
