Let's do this: We'll define a principle, let's call it "the Non-Evil Principle" (the NEP). We'll declare that our political ideology is in favour of doing things that are good, and is against doing things that are evil. Then, unbeknownst to others, we'll define good to be "political policies we like" and evil to be "political policies we don't like."
Once we're done with that, anytime we meet someone who recommends a political policy we don't like, we can taunt them with, "You're in favour of evil! You're in favour of evil!"
This will be fun!
