So this has nothing to do about holding leaders to a universal standard of moral behavior, and everything to do with Schmittian friend/enemy distinctions. Thanks for spelling that out, but if it's truly just a matter of "us versus them" then please spare us the moral outrage.
I'm not in the business of "moral outrage". We brought this disaster on ourselves. I don't blame unintegrated Turkish voters for voting for AK. Their behavior is indefensible but the consequence of our own failure: I blame ourselves for taking them in and granting them European citizenship. They are being hypocritical for voting for Erdogan and living in our free countries, but we are facilitating this hypocrisy by making it more attractive for them to live here than there.
It's very hypocritical blaming "unintegrated Turks" for voting AKP, while hailing the indefensible behaviour of some European counterparts. Yes, indeed, we must blame ourselves but not for the reasons you say. We must blame ourselves because we are losing the moral values attached to our condition of civilized European citizens. Those values that we used to take for granted. Democracy is a very fragile flower.
