There just needs to be careful consideration when making a permanent public message. No one gave a shit about historical or even contemporary oppression of people when most of these statues were placed. The Confederate statues were placed with the intent to oppress.
I think that's a misconception by the right of the left, that the left is excited to judge and hate someone for being wrong. I really don't think that's the case, more often than not because those jerks do exist, but the effort to be considerate is way more important. That self reflection is hugely important, no one is perfect and everyone has blind spots. Sometimes social norms and beliefs change. The important thing is the effort and the humility to look back and reanalyze.
