To that notion (you imported from Reddit), I'd say "it depends." I'll give 5% as a minimum level. I figure critical mass is a variable amount, depending on who the early adopters are, and how "attractive" the belief or behavior is.
Q has mentioned, "they thought you would follow the stars." Pop culture has more power, probably by definition, "popular." A small number of adopters there will bring along more of the public.
Or maybe even as much as 188%?
I think that’s one reason Kenye’s shift is so interesting as well as so alarming to the leftist hidiots.
