Obviously the best solution to this is to give her a gun while she’s teaching.
That would be a bad idea. We do have a horrible 1st Amendment that allows her to do her podcast without repercussions like being fired. Time to repeal that amendment too? Maybe we can avoid that problem in this case if she expressed these statements in school (as she said she did and lied to the principal) or discriminates against students. But do we ever want white supremacists in our schools?
