The statue won't disappear from the world. It just won't be displayed as something to be revered. Nothing wrong with taking it down and modernizing our history to include the unsavoury things that happened by the people who built the country. The whitewashing occured long ago... this is setting it right and acknowledging the flaws as well as the good.
Don't you believe it. The statue is gone for good. It will sit in storage until people forget about it.
We are just trading someone's truth for someone else's truth when in fact both are true. You don't acknowledge flaws by making them disappear.
