In an obvious hate crime against South Asians, this group manages to violate several of the Islamo-Leftists' cardinal rules. Not only are these people singing an actual Christmas song (no nonsense about obese trespassers dressed in red or Muhammad, Buddha, and Gandhi as analogues for Christ -- Liam Neeson, what are you thinking?), but they did it in a fast food court, in public, and they look happy!
Freedom of speech, assembly, and (possibly) religion, all in one excruciating apocalypse.
Merry Christmas!
