It's the same with vampire hunters. The days of such hunters are practically over, vampires and witches are both under protection of law because they both have human anatomy. They look like human, (usually) smell like human, generally act like human, and are classified as human, so regardless of the excuse murdering a vampire or witch is murdering a human.
Those who claim to be hunters are generally all talk trying to cause fear and if anyone should threaten you for what you do you CAN INFORM THE AUTHORITIES! And you should. Even if they are all talk. Nobody has the right to tell witches they can't be witches or kill someone for being a vampire, not even the government can get away with that, and anyone who threatens your life for being who you are has already broken the law by threatening your life.
Call the cops, press charges, and get a restraining order.
That's my advice.
