In Israel, Bein Hazmanim is hefker veldt for the kids. There is even a slang word for wanting to see the action, the fight, the protest, the dumpster fire, the police coming, the ambulance going. It doesn’t matter as long as it’s action. It’s called l’hitchardel”. So why should it be different in Brooklyn?
Separately, pooh-pooing these video clips, finding teirutzim galore, or worst, denying they are worthy of attention because we just don’t watch or read about Jews doing naughty things, weakens any argument on the topic under discussion. Forming a legitimate opinion requires information and knowledge. The topic is “Are the frum rightfully and properly protesting against discrimination in public policy, or are they damaging the public and themselves by their actions and overstepping the boundaries of legitimate protest?”.
