This is a charge often levelled against Calvinists. And while I (a Calvinist), see a lot of this in nasty sects like the (very muddled) Brethren, I regrettably also think it is true of Calvinists. Hair-splitting over theological minutiae, legalistic straight-jacketing, and "high looks" seem, from my experiences, to be in abundance in almost every denomination to a greater or lesser extent, but this charge of doctrinal pride and cold formalism, at the expense of humility, meekness and agape love, seems sadly true among many, though definitely not all, Calvinists.
