I bet it didn't bother anyone you had off from school for Columbus Day. In fact I bet you love this holiday because you got a day off. We celebrate the day Columbus discovered America (which isn't definitely true due to Vikings). However, you were never told in school what he did once he got there. Christopher Columbus and his men enslaved native inhabitants , forced them to convert to Christianity, and subdued them with violence (in some cases rape) in an effort to seek riches.
Congratulations everyone, we have a holiday based on a mini-holocaust celebrating a mini-Hitler!
But it's OK you didn't know . . . . ignorance is bliss.
