There is no rational reason to make absurd comparisons between working on Shabbos decades ago, on the one hand, versus walking around some plaza, on the other hand. And no reason to be motzi laaz on all those people who faced the pressure of feeding and housing their families.
You are entitled to your opinion on the efficacy of NK’s protests. So are they. But people are not entitled to call them “goyim” and other names as a result of their (biased and unknowing) opinions. People should be thanking them for showing the world the truth that Jews are not to be blamed for anything the Zionists do.
