It's unnecessary. No one cares about Columbus, anyway... no need to spend the effort tearing down statues (I'm too lazy to look up if that's even true, but... hypothetically). It's been a non-holiday in most of California for ages already. Celebrating him is dumb, but I'm not fussed enough about it either way. But, per someone else's comment:
" Everyone in the History of the U.S. has committed some "Crime" that is not to be Tolerated NOW!"
Yeah... no. This isn't like, "XYZ did amazing things and contributed greatly to our culture... but he once slapped a woman, so we should hate him". I'd agree that's dumb, but that's not the case here. With Columbus, it's a different matter... A bumbling buffoon who didn't know what he was doing, who committed mass genocide, and who didn't actually discover what he thought he did (he never set foot in what's now the United States, btw). He basically found a route to a place he thought was India (it wasn't), had nothing to do with discovering or colonizing the US, and killed thousands of people, never actually accomplishing the task he was hired to do (find a sea route to India). He was an absolute failure in every way (except at genocide - he was great at that, apparently). Throughout history, for hundreds of years, he was actually seen as a failure (if noted at all) until 1828 when Washington Irving wrote an intentionally semi-fictional biography of him. The only reason he's associated with America at all is because Italian immigrants to America, in the face of racism/hostility at their presence, took liberties with even Irving's story to justify them being in America by saying basically, "hey, Columbus was Italian like us!" It literally wasn't until the late19th century that Columbus Day, or Columbus' legacy even being considered relevant to American history, was considered a thing at all. So, if one demographic can work to introduce a holiday, arbitrarily per their own agenda, then another demographic has every right to try to remove it, arbitrarily per their own agenda. It's not like Columbus is actually a notable part of American history (he had nothing to do with the discovery, and centuries later if the Founding Fathers knew about him at all, it was as an historical footnote - nothing more).
