Its not abuse when the political opponent is a bigot using hate and violence to build a platform. For the millionth time, you are free to run out there, make an ass of yourself, and use all the slurs you want.
What you are NOT free to do, and what this entire conversation is about, is organizing and inciting people to commit a hate crime.

If you actually read the bill it verbatim says that criticism of a protected class is protected under free speech.
