The list of those who should not deech is a bit longer than that.

I accept you have your own homemade verb 'to deech' (should be 'to deach') and i accept that you mean to 'deech' means to teach incorrectly. Therefore it goes that teachers should teach and deechers should deech and never the twain shall meet!!?? So ,please look above at what you said. Because your English is so bad you tend to get more and more confused if you start trying to be clever in English and make yourself look stupid. Even I am embarrassed for you!
