I quoted #35 again because you pointed to it as me saying Columbus’s voyages were part of U.S. history. I didn’t quote it to imply you hadn’t responded to it.
Some people are wrong. I wrote that in the very sentence you quoted. This reminds me of a recent debate where @Exapno_Mapcase argued, because people disagree on the answers to any given religious question, religion can not exist.

New Year’s Day isn’t part of US national identity. It’s an international holiday.
I think it’s both.
