happy imperialism day!

I've always been a big fan of giving holidays much more accurate names. For example, Columbus Day could be:

• Imperialism Day
• Indigenous People Extermination Day
• Second (or Third) Person to "Discover" America Day
• Claiming Lands That Don't Belong To You Day
• Sticking Flags in the Ground Day
  

I'm sure you can come up with some more good ones!
