I think it might have to do with how one is educated Faldage.

The aitch/haitch thread is a good example. If you are taught that saying haitch (by your parents, teachers, etc) is wrong, you believe it. When you then hear the word pronounce incorrectly (as per your educators) it doesn't sound right in your ears and is grating.

It may also be that whole "fear of the unknown" thing of your clan ('s way of speaking) versus my clan ('s way of speaking).
