Well, here october the 12th is also celebrated, but often holidays are changed to Mondays to make the weekend longer. So it is today. I think it should be banned. Colombus may have been a good man who only sought a way to India. It is said that he was Jewish and postponed his journey one day to fast on Tisha beAv.
But the day was made a holiday by Europeans who conquered Amerindian Lands, killed our natives and kidnapped thousands of Africans to be slaves in America.
