I'm trying to say...it's not even the religious implications as much, although I will admit, religion is a part of culture that has historically been the most imposed onto people. Mostly, I dislike the cultural implications. That the only cultures the prison finds valid are Japanese culture or 'Western' Christianity.
Everyone being introduced to Hanukkah could be just as enlightening and entertaining. Or Diwali. Or Sxeltu. Or Pinteron. Or any of the multitude of other cultural and planetary holidays there are out there!
