Don’t: “HANDS OFF HEALTH CARE!” and “READ THE BILL!”
Do: “I LOVE YOU, BARACK!” “AMEN!” and “YES WE CAN!”
Also permitted: Shouting at historic inaugurations to protest war (as legions of Code Pink activists did in 2005 during the president’s address) and shouting, “We didn’t cross the borders, the borders crossed us!” to protest immigration enforcement (as thousands of illegal alien supporters did during raucous rallies in 2006).
Do refrain from boisterous shrieking against those who accuse you of lacking patriotism – unless you are Hillary Clinton, who bellowed at the top of her lungs in 2003:
“I am sick and tired of people who say that if you debate and you disagree with this administration somehow you’re not patriotic. We should stand up and say we are Americans and we have a right to debate and disagree with any administration.”
