No, but where are they gonna learn all those things? These concepts are transferred through social contacts, and they won't acquire them when they are isolated.

And learning about things is as much about saying what i think as it is about getting feedback to that thought process. It's not to say that people shouldn't try to get some basics about stuff before uttering crap, but if you want the younger generations to actually engage with social concepts, it does not help if they are excluded from the discussion.
