People self segregate based on other characteristics, too, say nationality and language. Hence all the China Towns. There are even remnants of Czech communities in places like Texas that still dance polka and bake kolaches. And Czechs abroad generally assimilate fast.

Yet racial diversity at universities and in corporations is highly sought after and supported by all kinds of measures.

Perhaps political diversity should be added into the mix. It would be consistent.

I always thought kolaches were Mexican, because I'd only seen them in Texas. I learned something new today.

Note that there is some confusion! In South Texas especially, the dish klobásník (informally "pigs in a blanket") is very frequently labeled "kolache", [1] despite having little resemblance to the traditional desert:

And yet that did not occur. You have all the crazies on 4chan too, did that enable law enforcement to stop the New Zealand Mosque shooter, who was a regular?

New Zealand shooter was on 8chan and he was a lone wolf. Those are not easy to prevent but a mass discussion of a large coordinated event definitely can be.

So just ignore the slew of other violent crimes that were prevented by federal law enforcement monitoring anonymous message boards?

Thats not what I said.
