So there were some pretty wild protests in Denver this weekend about a Columbus Day parade:

Police arrested 83 Columbus Day Parade protesters including American Indian Movement activist Russell Means after fake blood and dismembered baby dolls were poured on the parade route Saturday.
...
Denver's parade, which was started in 1907, has a troubled history of arrests and confrontations between Columbus supporters and detractors. Protesters have called him a slave trader who touched off centuries of genocide and oppression against native people. Supporters say he was a brave explorer who opened a new world and that the parade is an American holiday to be celebrated.

If they think that they can eliminate the Columbus Day holiday all together, then they've underestimated the wrong group of people.  Not Italians mind you... postal workers.  If you think you'll be able to eliminate one of their day's off, you're dreaming.
