"Sparhawk on Monday expressed regret for shouting an anti-gay slur at a protester during the incident. “I said things I shouldn’t have in the heat of the moment,” he said. “That doesn’t express my views.”

Oh, I think his views are exactly what we saw in the "heat of the moment."  The protesters should not have harassed this bigot, but we should understand that this guy spewing anti-gay bigotry is standard operating procedure for most of these guys.  It's my experience that these types of guys are often the ones driving aggressively.
