Link to the post in question.

I had to swear to defend the constitution from all enemies, foreign and domestic, etc., when I joined the US Navy, but I wouldn't expect a college teacher to have to do the same.

So does this mean that all Cal State University instructors are accountable to take up arms against any aggressors? What if another school shooting happens- will teachers be fired if they do not react accordingly and try to subdue an aggressor with a machine gun?
