In extremism, making the extreme the norm is end game. Whether or not end game is where the extremist is at, it is always where they live. Even when all evidence points to the contrary, they believe they speak for a silent majority that secretly agrees with their particular brand of crazy.
& that is why MarjaE placed ‘centrists’ in between the funny marks.
edit to add - In the US there is enough support for any particular brand of crazy to give some merit to any extremist believing they are at end game. It seems increasingly that the greater impediment is less the silent majority (that doesn’t really agree with the crazy) than it is merely the other extremists.
