Neturei Karta engages in peaceful protests – note the great approval one hears of them from the people complaining about Peleg. Whether peaceful, non-violent protests (cf. Gandhi in British India, Martin Luther King in the American South under Jim Crow, the “White Rose” in Nazi Germany) are effective is a matter to debate.
Remember, the alternative to protests is repression, i.e. gestapos and camps, gulags, “re-education”, When you look at it that way, democratic tolerance of disorder doesn’t seem all that bad.
