This is more of the usual racist harassment of Asian businesses that guys like Al Sharpton got famous off. But it also undermines the left’s great united front against ICE and for illegal migration.

Protesters in Brooklyn — some chanting “where is ICE?” — besieged a second nail salon Monday that they believe is connected to the shop where customers brawled on video with employees last week — forcing cops to escort the workers out for their own safety.

About 150 predominantly African-American demonstrators marched from New Red Apple Nails at 1426 Nostrand Ave. — scene of the melee caught on tape Friday — to the Beautiful Red Apple Nails at 1224 Nostrand Ave. and trapped four employees inside.

It wasn’t immediately clear if the two salons are related. But police were ready for protesters and were inside the business when they arrived at about 6:30 p.m.

Demonstrators angrily chanted, “shut them down,” “f–k the police” and “no nails, no toes, these racist shops have got to go.” At least one protester screamed, “where is ICE (U.S. Immigration and Customs Enforcement)?” implying that the salon’s Asian employees might be undocumented immigrants.

The conjunction of “F___ the Police” and “Where is ICE?” says it all.

Nail salons in New York tend to be Asian. And many of the employees in such businesses are illegal aliens. Conflicts with Asian businesses in African-American neighborhoods are commonplace. And, despite the left’s imaginary multicultural big tent, the various groups under it don’t actually get along with each other and don’t actually like each other.

And black people are often not on board with illegal aliens.
