Note that the way you phrased that, "You are evil unless you pay me reparations." makes it so that the person isn't considered evil if they pay. That is significantly different to "You are evil therefore you pay me reparations.", in which the burden of proof of evilness is not based on payment. The person is still considered evil if they pay; they pay because they accept that and want to make things right. That's important.
Your link doesn't support your assertion that the phrase "I hate evil people. You are evil unless you pay me reparations." meets the definition of the crime of intimidation.
Should the state jail someone for saying that?
