I think there's also the point that if those lines are used in the right context -- i.e. someone who is genuinely interested, and isn't arrogating e.g. the Right to Education to themselves, they're probably OK. It's when they're deployed willy-nilly and/or accompanied by the attitude suggesting in Derailing for Dummies, AIUI, that they're most harmful.

But I could be wrong. I don't tick many point-scoring boxes either ;-)
