"Awareness" is almost never the limiting factor to policy change.
This is why awareness based movements such as occupy, BLM, and climate protests go nowhere. Everyone is aware of climate change, police brutality, or inequality.
Organized opposition with leverage and a compelling alternative is the bottleneck. Awareness isn't a policy position and doesn't advance debate.
Luigi did not have a thesis capable of changing minds. I dont know and haven't seen a single example of someone having their mind changed. Just people more fired up on their priors.
