Of course he was. And, Palin's use of crosshairs on targeted districts in the 2010 election was a metaphorical use of warfare, as well. Incidentally, so is referring to a state as a "battleground" state.
I don't care about warfare imagery--heck, the very word "campaign" has its roots in warfare. It doesn't bother me. I've defended and will continue to defend going as far as hanging/burning politicians in effigy as a manner of protest.
What does bother me is the blatant hypocrisy on the left concerning the use of warfare imagery. Many of the same people, including those on this site, who decried Palin's use of crosshairs--who said that it would or could incite violence--are noticeably quiet about Hoffa's warfare language. The same people who gripe about the Tea Party will be conspicuously quiet about Hoffa's language, the
Tea Party Zombie killing game, or the recent
Union Thugs and their destruction of property and holding of security guards.
The Union Thug action is the only part of the above that I oppose. Yet, I don't expect a peep out of most of the Hype leftists about any of it . . . you know, the same ones who would fret and bellyache about the "violence" behind a guy holding a poster at a peaceful Tea Party rally that says, "Hands off my guns."
