That's hilarious. People are silly. Anyone with critical thinking skills should be able to deduce that not everyone uses the same date format. While I am from America I support your original statement. Stupid Americans! There are a lot of them. Or really I think it's ignorant Americans. The fact that people got confused by this and thought the OP was referencing December 6th is laughable. Not to mention if they did get confused, they could check a calendar and see that the 6th of December is a Sunday and Xur would be gone.
