Extremism, Commitment Ceremonies, and Effective Rebuke

Since there is discussion on Mishmar and elsewhere about the zealotry of extremist elements in the charedi community, I wish to reflect on the concept of effective tochacha, or rebuke. The connection is obvious: acting violently, or in an anti-social way is done to protest acts of evil. However, upon reflection, such conduct is seriously flawed even on its own terms. See link.
