The Power of Swear Words.

Lulz.

There's nothing funny about it. You specifically omitted the age I said they begin learning it.
At no point did I say eight year olds were in kindergarten. This is not Shenanigans. Do not spam.

This is true within the confines of a single culture.

You're mistaken. It remains exactly true. The fact one party is unaware of the meaning in the other culture does not change the fact it's the cultural meaning behind the word that makes it negative. It's still the context of the word, regardless of the speakers ignorance of that context, that makes it offensive to the offended party.

Just because I don't know gnorshleboggle is a deathly insult to your culture doesn't mean the implications of that word aren't what offended you by my using it.
