This is the #Occupy and Anti-Israel mentality. These people think stopping others from expressing their views and destroying property is an acceptable way to express their own opinion. They think they have the right to judge speech and then censor it if they disagree.

From the New York Post:

Cops busted a lone protester -- angry with subway ads equating enemies of Israel as “savages” -- as she spray-painted over one of the controversial signs today. A Post camera crew captured the bizarre conflict between suspect Mona Eltahawy, 45, and a woman defending the ads.

“Mona, do you think you have the right to do this?” said Pamela Hall, holding a mounted camera as she tried to block the barrage of spray paint.

“I do actually,” Eltahawy calmly responded. “I think this is freedom of expression, just as this is freedom of expression.”

Hall then thrusts herself between Eltahawy’s spray paint and the poster.

Eltahawy -- an activist who has appeared on MSNBC and CNN -- engaged her in an odd cat-and-mouse dance, spraying pink every time she had an opening.“What right do you have to violate free speech,” Hall pleaded.

“I’m not violating it. I’m making an expression on free speech,” an increasingly agitated Eltahawy shot back.

“You do not have the right!” Hall said.

“I do actually and I’m doing it right now and you should get out of the way! Do you want paint on yourself,” Eltahawy shot ack

As the poster defender bobbed and weaved to get in the paint’s way, Eltahawy mocked: “That’s right, defend racism.”

Finally an MTA police officer and an NYPD cop came to scene and arrested Eltahawy.
