How true. If one's parents skinned puppies and sold their pelts for a living and one grew up to be a vegetarian who hated them for it, one would likely still have a hard time tolerating other people later in life ridiculing or criticizing them.

I think it's because we see our parents (usually) as ultimately good people, and when people criticize or ridicule our parents it feels like they are suggesting the parents are not good people, even if that's not what they mean.
