I would argue that there are some very large differences between political invective and racial/sexual etc. Calling you a Nazi might not be accurate, much as how calling me a Marxist-Leninist wouldn't be, but I would not categorize that as a slur.
The problem with that, of course, is that actual legal trouble could come down on the head of the site. It's not just a moral question, because advocating murdering police is not something that most states would look kindly upon.
I feel like there are a number of Memri TV jokes I could make, but I will instead simply say "hello there" and hope that the new civility kick works out for you.
