I mean putting your kids in public school is akin to sending them to play on the freeway, psychologically at least. If you HAVE to send your kid to a public school, I'd say go somewhere that isn't "nice" and isn't ghetto enough to be scary and hope for the best. This shit really is everywhere, it's breathtaking how fast it has spread, but you're out of the frying pan and into the fire if you dump your kid off at the door of a place full of the upper middle class twits' progeny. Look at Loudoun. It's the "nice neighborhood" morons who are driving us off this cliff. All the effete globohomo middle managers, the doctors, the lawyers, the indeterminate variety of brown NGO director she/ella.
It has infested everything and everywhere, but the social pressure is going to be so much worse for a kid going to school where everyone is supposed to go to an Ivy. Especially if we're talking about an actual lower middle class white kid whose parents just want them to break into that bracket, not a scholarship-friendly brown exotic or actual elite.
