I don't think we're dealing with unrepentant assholes here. We're dealing with inconsiderate idiots. "Never attribute to malice that which is adequately explained by stupidity." I know I've hurt people out of stupidity my share of times.
St. Bernard of Clairvaux once said the the cardinal virtues are "humility, humility, and humility." When we see bad things in the world, we should try to correct them, but we shouldn't automatically assume that the people doing the bad things are always bad people. That is, unless we're all bad people too?
