The dozen or so times I engaged with PK, though we often debated to finite detail, we managed to remain civil to each other. Maybe it was the sake of namesake, or something.
Very few people will continue to frequent this place with any great regularity once they truly start to get it. Anyone who is here regularly is only here because they still have things to learn, whether they realise or accept it, or not. Maybe this is the one thing PK didn't understand, not unlike others, is that he still had/has things to learn. We all do, to varying degrees. And that, rather than criticism, is pure observation.
