The Circle Slash Means Stop, Doesn't It?

So does adding the word "Stop" to a circle slash make this ad say "Don't Stop"? And why are the last three letters in "capitalist" underlined? Is this a take-off on anti-capital punishment groups? WHY? Just to be punny? (At least they know how to use the circle slash symbol) And why is the drop shadow so huge on that button? And why can't an organization that can afford to run a quarter page ad in the national version of The New York Times afford to hire a team to create a decent ad?
