Why we should preserve all historical monuments, however offensive.
Statues, monuments, and all things we create are reference markers of history. They serve to remind us of where we were, and where we are at now. The progress, or lack of civilisation can be measured against them.
Items and features causing offence, remind us of the offense.
When they are erased, history can simply be re-invented, for similar offenses to be repeated all over again in the generations that follow.
We only have a limited number of attempts to get it right, to assure our future as a species. Time we stopped making stupid mistakes.
We owe it to our children to leave them with a true clear view of the way ahead.
