All I’ll say is pick your battles wisely. Don’t try to convince some random Right wing weirdo in public, they dig into their positions and don’t listen. If someone is willing to listen to you, try to give them basic not too scary stuff at first and slowly push China as a better alternative to the status quo, but you need to know your shit, and especially know what’s not true because most people in the West know mostly lies about China, very little from China actually gets here without heavy criticism. Climate change can also be a good topic, the capitalist system relies on “line go up” mentality, infinite growth, finite supplies, increasing numbers of climate disasters around the globe. Like I said, start out simple, most people won’t listen to someone quoting Mao from the get-go.
