I agree with gjm that evil does not necessarily require coercion. Contemplate, say, instigating a lynching.
The reason EAs don't do any coercion is because they don't have any power. But I don't see anything in their line of reasoning which would stop them from coercing other people in case they do get some power. They are not libertarians.
