Bait-and-switch redpill memes show us that, sometimes, conveying a message indirectly can be more effective than more explicit/direct approaches.
Reading this great post from @Javik2186, I stumbled upon this graph, and an idea appeared:
Due to ((mass media)) indoctrination, most people will have resistance against the idea of increasing natality to prevent white people being replaced. However, the graph gives us a chance to reframe the problem: "if we don't have children, liberal people are going to be replaced by extremely conservative people". No doubt a "normal person" will react to it differently.
I think it is an idea worth exploring...
