> incredibly impoverished in his personal world view

Translation: I think X is important, he thinks Y is important, therefore it's not merely a matter of having different priorities, but "he is wrong" and - worse than that - "his worldview is impoverished".

I love how "tolerant people" can't tolerate people.

Moral priorities will always be subjective. There isn't much sense to prepending "I think" to a sentence when it's implied by the context.

Being tolerant doesn't mean that one cannot be critical.

Being critical doesn't mean that one cannot be respectful.
