Pink is sometimes used by Social Democrats, such as in France and Portugal. The more traditional colour of social democracy is red (because social democracy is descended from the democratic socialist movement), but some countries have large social-democratic parties alongside large socialist or communist parties, so that it would be confusing for them all to use red. In such cases, social democrats are usually the ones who give up red in favor of a different color. Pink is often chosen because it is seen as a softer, less aggressive version of red, in the same way that social democracy is more centrist and less militant than socialism.
In some European nations and the United States, pink is associated with homosexuality and the pink flag is used as a symbol in support of civil rights for LGBT people. This goes back to the Nazi German policy of assigning pink triangles to homosexual prisoners. Pink is the color of the feminist party Feminist Initiative in Sweden. WIKIPEDIA
Sen. John McCain lashed out at protesters during a congressional committee hearing Thursday, hurling insults at the lot and kicking them out of the chamber.
“Get out of here, you low-life scum,” the grizzled 78-year-old Arizona Republican told a group of anti-war demonstrators calling themselves “Code Pink.”
“You’re going to have to shut up or I’m going to have you arrested,” he said.
In the middle of the hearing — a Senate Armed Services Committee panel on national security — the protesters approached a witness table where former secretaries of state Henry Kissinger, Madeleine Albright and George P. Shultz were testifying.
“Arrest Henry Kissinger for war crimes," chanted the protesters, who were also carrying large banners calling the 91-year-old Kissinger a war criminal.
The melee went on for more than two minutes, prompting McCain to lose his cool.
"I have never seen anything as disgraceful and outrageous and despicable as the last demonstration that just took place," he said.
Capitol Police eventually removed the protesters from the room.
McCain defended his rebuke of the protest on FOX News Thursday afternoon.
No American citizen testifying before Congress should be subjected to such @CodePink intimidation, esp not a 91-year-old former Sec of State

"It was terribly upsetting to me. Frankly, when someone does almost physically threaten someone. I do believe they should be arrested. If they want to demonstrate and be thrown out, that’s one thing , I don’t like it, but I have never objected to it, but what they almost did to Dr. Kissinger is beyond the realm of decent behavior in my view,” he said.
“They can say anything they want to and yet when people physically threaten an individual - that’s not what America is supposed to be all about, that’s not what our laws are about and that’s certainly not the way that the United States Senate should have the ability to conduct a hearing so that we can inform the American people.”
