You can claim that anyone who even hints that maybe two countries with very different demographics may in fact have differences due to those demographics is racist and that any comments along those lines are just inflammatory flamebait, but people will continue to ponder that theory because 1) it seems fucking obvious and 2) curious people (and people in general I guess) can't help but be interested in topics that they're told not to be interested in.

Now that you (and others) have flagged the thread, the people with showdead on will see that it has happened yet again, and they just might seek out a place where an actual discussion can be had.
