โ€˜Every once in a while, you need to get out on the streets and get a little bloody when necessary,โ€ Rep. Michael Capuano (D., Mass.) told a February 22 union rally in Boston. Even if union members and their supporters missed Capuanoโ€™s call to mayhem (or his subsequent tepid apology), many of them are on the same brutal wavelength.

Although Rep. Gabrielle Giffords (D., Ariz.) still is recovering from a January 8 assassination attempt, the Leftโ€™s post-Tucson civility campaign has vanished like gunsmoke in a desert breeze. Rather than make nice, labor activists and fans star in YouTube videos, preaching and perpetrating violence.

YouTube shows a young, bullhorn-wielding Teamster heading menacingly toward Stanhope.

โ€œI told this guy, โ€˜You need to leave,โ€™โ€ Stanhope recalls. The Teamster then โ€œtook a punch and knocked me back about two to three feet. I felt my hand was in pain. I stepped back up, and he threw another punch at my throat.โ€

After eventually getting local police to issue a battery citation to Teamster Richard Andazola, 28, Stanhope received first aid for his swollen hand and headed for a hospital.

โ€œI went to the emergency room and got X-rays,โ€ Stanhope says. โ€œIt was not broken, but I had contusions.โ€ Four days later, his hand still hurts after a few hours of typing on his computer keyboard.

โ€œOut of nowhere, all of a sudden, I get slammed to the side against a wrought iron fence and down onto the pavement, by one of these guys who wanted to push through,โ€ Greene said online. โ€œThe guy came through and cold-cocked me from behind,โ€ Greene recalled, and the blow slammed him into an older woman who stood nearby. โ€œWhen he shoved me, he shoved her, too.โ€

โ€œI have been involved in activism at the grassroots level for many years,โ€ Greene added. โ€œThis is the first time that I have ever been physically assaulted personally at a protest or counter-protest.โ€

Like a Labor Day parade in reverse, unions are losing ground. They represent a shrinking share of Americaโ€™s workforce. When their Democratic allies in state legislatures decide to show up for work, they have started losing votes to right-size their privileges. The โ€œlaborโ€ movement looks like a leisure movement, given union activistsโ€™ evidently infinite time to abandon their classrooms and other work sites so they can scream in the streets. And now they have revealed themselves as the Brownshirt element in Americaโ€™s public life.
