This is a huge nightclub in Turkey.
Reina means “Queen” in Spanish, and it looks like quite an important place. I assume the people who were partying were mostly Turks and mostly Muslim, but judging by their dress, they were not Muslim freakoids. The problem is that “real” Islam is practiced only by Muslim freakoids, and they unfortunately have the weapons and a heck of a lot more viciousness than anybody else. And, of course, they have the support of the US government and the world leftist press.
