I pick at my co-workers all the time about Columbus Day and it being a 'US Holiday'.
I sometimes humorously feign 'anger'
(Liberal social justice outrage
) and ask them why we have an official US Holiday celebrating a European explorer sailing for another European country setting out to try to find the West Indies, getting lost, failing to do so, landing instead in the Bahamas, enslaving half the natives they come across, killing off the other half (disease, etc...), and then they give him credit for
finding AMERICA (not the Bahamas)....especially when the Viking, Leif Ericson, was the 1st one to
find America years earlier....despite the fact that it was never
lost because my people had been living here for a loooooooong time already.
