The West is currently being invaded, not by Germanic tribes [as were the Romans], but by ideas created by the largesse of Western freedom. To some degree, the West invited this invasion because it has been too lazy to think through newly presented ideas or recycled ideas in newly minted format. And, when the West did think through them, it has been too lazy to mount a defense, present a reasoned alternative, or at the very least, offer rational limitations to irrational concepts.
