“H&M does have a right to be notified that their ad was offensive in that community and that the owner of the space should have informed them of that.”
Agreed. H&M is a huge multinational corporation with tens of thousands of employees. You can’t expect them to know the demographics of every block in New York City.
And it is currently being boycotted by the anti-Semites because they have opened stores in Israel! It deserves our support, not the destruction of its ads. The community should raise the money to pay them for the vandalism, and to buy them out of their contract for the billboard. (Actually, the bocherim themselves should pay, but they may not have the money.)
