Hi Jura: If the offense is on purpose - very bad and whom stay as unpolite are them. I agree that sometimes when learning, something can be said wrongly and without purpose, so here tolerance is the key word. I do not agree with those that say that because this is a free world, anybody can say whatever, no way - first rule to live is to respect the others and never do something that you don't want for yoursel. Now Yura, we the grown ups, have to learn to deal with some unpolite people specially the youth now so irreverent, but we can tell them what is expected or not in the seek of politeness (at least). Anyway, the result is that everybody should disagree with offenders, right?
