I’m a firm believer in the use of covert persuasion against the far left. Frankly, I think they’re a more fertile ground for persuasion than is the mainstream conservative. To subvert a leftist you honestly only need to do one thing:
Make them love SOMETHING, ANYTHING, more than diversity. It doesn’t matter what that something is. It could be walkable cities, high percentages of non-overweight attractive women, safe mass transit, a clear environment, their own children, the list goes on and on.
Once they love that one thing more than diversity, it is only a matter of time. In leftist spheres, where obviously I do not go by the name of Jehu, this is my strategy. Find what they love that isn’t diversity, and try to enhance their love for it until it becomes a greater ‘god’ for them than diversity.
