David el Gnomo, you're welcome. But I didn't write much of anything about White/White racism and I'm not sure that the Black/Black taunting actually qualifies as "racism".

Be that as it may, my central point was that ostracism happens for a number of reasons [in the USA] during school lunches and recess [and also in colleges/universities] and I don't think that administrators should enforce a no-ostracism rule during those times.

That said, I would of course prefer that it doesn't happen, but this forum is proof that people often self-select leisure time activities where we are not "the only one" or where we aren't "one of only a few".

None of this should detract from the point that all forms of taunting are wrong, and also this shouldn't detract from the point that the police shouldn't be involve as a matter of course as a consequence to racial or other forms of taunting.
