> Exposing yourself to things you dont agre with is what helps us all question our own beliefs and prejudeces, and grow as people.

I have another wise-sounding soundbite for you: "I disapprove of what you say, but I will defend to the death your right to say it." —Voltaire. All this sounds dandy and fine, until you actually try and examine the beliefs and prejudeces at hand. It would seem that such examination is possible, and it is—in theory, whereas in practice, i.e. in application of language—"ideas" simply don't matter as much. Material circumstance, mindset, background, all these things that make us who we are, are largely immutable in our own frames of reference. You can get exposed to new words all the time, but if they come in language you don't understand, it's of no use. This is not a bug, but a feature, a learned mechanism that allows us to navigate massive search spaces without getting overwhelmed.
