I thought that was the Bee. There's a proper response for what passes for Islamic 'human rights':
January 20 would make more sense than January 27. Auschwitz was a big one, but there were others (6 death camps, 23 major camps, and about 1500 total concentration camps.)
January 20 is the anniversary of Wannssee and would honor all the dead, not just the ones that were killed at a single location.
Looking at some numbers, while more died at Auschwitz, it also had more survivors. So while ~1,100,000 died at Auschwitz and only 925,000 at Treblinka, Auschwitz had about 200,000 survivors and Treblinka less than 100 total.
