I didn't catch the sarcasm. In these days of Michael Savage, it's getting harder to separate the sarcasm from the firmly held belief maquerading as sarcasm. My apologies if I've given offense.
As for physical violence. Violence except in a legal context (such as self-defense and military force) is criminal activity. I'm not a criminal and simply don't have a shared frame of reference to explain the actions of criminals.
A criminal who shoots up a political office is no different in my view from someone who shoots up a day care center. And should be handled in the same manner.
If caught, such criminals should pray that I don't end up on their jury. They'll find that I couldn't care less what their political affiliation is.
