The last time I checked it was leftists (see: Occupy Wall Street) who had a serious penchant for violence.

Florida Democratic Rep. Alan Grayson doubled down his extremely provocative rhetoric on Wednesday, in the days after his campaign sent out a fundraising email with an image likening the tea party to the Klan that showed two Klansmen in the background with a burning cross used as the “t” in “tea party.”
However, Grayson took his tea party-KKK comparison another step further and said the tea party engaged in hate speech, racism, discrimination, bigotry and in some case even threats of violence.
“I think the tea party should expel those members who engage in hate speech,” Grayson said to an unidentified reporter with Orlando ABC affiliate WFTV. “So many members of the tea party have engaged in hate speech against the president, against the first lady, against numerous members of the Congress and against me. And we could give you examples of that.” […]
Grayson was also asked if the comparison was unfair since the KKK would use violence and that the tea party has shown signs of using violent measures. According to Grayson, they haven’t yet but the presence of certain weapons at presidential events.
“Not yet,” he replied. “You may recall that there were people that brought automatic weapons to president’s speeches. What were they trying to convey? They were members of the tea party.”
