No, we do not have the legal right to vandalize. We may, however, have the halachic right to. Then it’s a just a question of what you put more by, the American law or the Torah.”
I follow “Dina D’Malchusah Dina” as per Halacha. Our Dina states that it is a CRIME to vandalize, and the Halacha states we have to abide by the rules of the State. No one told those guys to look up at the picture. it was not an untzniusdig picture according to standards set forth by law of the land. You don’t like that – move somewhere that is more to your liking, or somewhere over which your opinions and halachioc observance are allowed to prevail. Until then, you have to live where you are, and that might include the goyim who live around you, who by the laws of this land (a land which gives us ALL freedom of religion)are allowed to post pictures that are not obscene (and they are NOT, even if they are of a different tznius standard than your own)and have a reasonable expectation that no one will damage their property.
