It's a warning from Hashem and its only going to get worst whether it be nazi wannabes or commies or whoever else. The traitors who govern Israel and all the self hating leftist liberals who support them are immeasurably bigger threat to Jews than these pretend nazis with their made up flags who can only dream of having a heritage as great as ours. If most Jews were half as fanatical about our heritage as those losers are about their pretend one we'd finally raise to level of being normal.
