How is any of what I said filial piety though? I get that unquestioned authority can lead to abuse, having experienced it myself and I don't practice it at all, but the naming conventions for the Vietnamese and Japanese languages don't relate to that.

If anything, it's a form of social structure - if you're an acquaintance, you're referred to in a certain way that is widely considered polite and friendly, if you're being aggressive to someone you are referred to in another way.

I don't know. I just like things orderly and easy to understand. Taking all of the above away just makes social interactions much more tedious.

Edit: just reading back on the chain of communication, I'd like to clarify that I agree with the age based discrimination should be changed but wholeheartedly disagree with removing the polite honorifics. Nothing wrong with being nice, unless the person deserves otherwise.
