Because if their parents won’t teach them, and their peers won’t teach them, and certainly their teachers won’t teach them, then apparently we’re counting on random passerby to teach the Hard Left to stop acting like deranged Lovecraft cultists. Which we can do; but I suspect that the recipients of this particular form of remedial education won’t enjoy it much.
