But do those "classes" regularly insult each other on Usenet or
any other place, repeating the same words over and over? I
seriously doubt it.

Remember, _I_ don't make the division between classes of posters
here at sci.math. The posters _themselves_ make the division by
insulting members of the other class.

If you don't like the division, then you can try to convince the
_insulters_, on _both_ sides, not to be so divisive.
