Jehova's Witnesses delegate their relations with society to a hierarchical organization more than, say, Roman Catholics? Seriously?

No, but there is greater social interpenetration with the rest of society, and some of the more explicitly coercive practices, such as shunning apostates and heathens, are less widespread.

Jehova's Witnesses uses cult tactics to recruit, induct and retain membership. The Roman Catholic Church works more like a transnational corporation. It's not obvious that one is more harmful, or even less coercive, than the other. But the harm and coercion by the latter is (usually) much less flagrant and obvious.
