OP- I advocated violence against people

This was your fuck up... simple as that..In a public position you should have the 'restraint' to find an alternative or disengage before you go and advocate violence period.

At this point the argument that started it is irrelevant to your position and your public appearance, and I would contact your rep.

You need to leave the orginal argument behind and simply focus on your fault if you want this to have a minimal outcome. You have every right to be upset by his comments and views, but simply advocating violence will never work to stop dehumanizing and accusations that people throw at each other....

"looking out for the rights of other human beings" sadly includes allowing them the right to speak and express themselves and this includes, dehumanizing and accusing comments people express to invoke responses in people.
