My Twitter feed today:
"Why is this a holiday? Columbus was a horrible person."
"And the continent was already inhabited. He didn't discover it."
"Let's celebrate Columbo Day instead."
"Howabout this historical figure? I like him."
"No! He's also a monster!"
"Happy sanctimonious self-righteousness day! (Directed at both sides)."
"Sure, it's easy to call out Columbus, but you don't feel bad enough about the REAL oppression that you enable by existing!"
... Hey, look, we found a way to make Monday ineffably worse.
