@Neira - For largely the same reason I feel Revvy's 2-line idea is not a real solution.
This hardly provided any further information (comparable to the opening post of this thread).
I'm not going to work my way through the pages of this thread where one might be able to find additional information as to what your point of view may or may not be just because the opening post failed to make an argument on its own.
Additional channels will just separate the already small community more.
Segregation as by your idea stands against a marginal amount of decency if we're following @Revvy's proposal.
You're either supporting segregation or believe people are too illiterate and wilfully disruptive to have the tact adjusting their posting manners in an appropriate way.
Take your pick.
