Saying something negative about someone's behavior is not a slur, but I guess we'd be fighting a losing battle to try to make that distinction.
You are absolutely correct but the left has damaged the English Language so badly people fail to see the significance. It's like using the terms republic and democracy interchangeably. When I hear politicians saying our "democracy" it just makes me cringe to think how little they understand the language.
There is danger from all men. The only maxim of a free government ought to be to trust no man living with power to endanger the public liberty.
Public virtue cannot exist in a nation without private, and public virtue is the only foundation of republics. There must be a positive passion for the public good, the public interest, honour, power and glory, established in the minds of the people, or there can be no republican government, nor any real liberty: and this public passion must be superior to all private passions. John Adams
