I was taught them. Keeping this "secret grammar" hidden from Japanese (especially adults) is going to wind up seperating us and eventually I am going to find a way to educate Japan about it without doing it in a professional setting. Then this issue can be put to bed. (I'm pretty passionate about this issue so sorry if I seem wacked out) Anyway, I think high school seniors should be taught this as curriculum and that the private language schools should have optional units on the subject.
I have my doubts about how certain you are about the separation part, particularly from the sheer amount of media, meaning TV, movies, etc etc etc, that comes into Japan from the west.
Are you saying you want to try and teach profanity in an
unprofessional setting? ?
You know when you do get around to teaching about it I seriously hope that you also teach them that they will be quite possibly taking their own lives into their hands if they use profanity at the wrong place and the wrong time. That is no joke either. Are you also going to teach them about the use of the seriously discriminatory "N" word? Yet how are you going to explain or teach them that in some sections of society some black people will use that term as a greeting or a term of endearment. How are you going to teach them the difference.
Or are you only going to limit your choice of vocabulary to the 7 words you cant use on TV; Shit, Piss, MEXT, Cunt, CockSucker, motherMEXTer, and Tits?
I will tell you this if any Japanese person came up to me and greeted me with a "what the MEXT's up?", I will either rip out his throat or fall down laughing my ass off.
I dont think it would be appropriate to teach even adults the use of profanity
UNTIL they have enough of an understanding of English to include colloquial English to include idiomatic English. To get them to understand that just because you can use it doesnt mean one should.
Get this though, I understand and agree with your point about teaching it, but I disagree about your thinking of it being done in an informal or unprofessional manner.
