People can't just erect monuments in public spaces without council or government approval. Normally this allows for objectors or protestors to have their say in preventing the project from being approved. What people put on private property is different issue.
Sure.
Now explain how that worked in Reconstruction South and Jim Crow South.
Doesn't the South allow people to lobby their representative? Or if they feel strongly enough, organize peaceful demonstrations? The risk, of course, is that these could be hijacked by extremists of all persuasions. The idea is to pressure councils to review their monuments, to reflect the wishes of the majority.
But what if the majority of people in a city want their public monuments or statues to stay?
I just checked your profile and I think you are in Australia. I didn't know and perhaps I am wrong. I was operating under the impression that you are American and understand the different levels of government and were familiar with US history and understood what Jim Crow and Reconstruction were. I thought perhaps you read some of the links upthread that detail the history of most of such monuments and statues. I think I was wrong and I apologize.
It is not necessarily true that petitioning the local government (city or town) is going to get a statue taken down or moved. Those statues and monuments were erected mostly by small local civics groups or by wealthy donors and local governments (and universities) are loathe to seem ungrateful to wealthy donors.
As for majority rules? Well, in the South, a great majority of the electorate (white men) were very much in favor of keeping black people slaves. We had a war about it. They lost.
As I wrote upthread: Imagine you are a Jew in Germany and every day you must pass a statue of Hitler on your way to work or school. How would that make you feel? Would it make you feel better or worse if Jews were a minority and the majority of non-Jews had no problem with that statue of Hitler? Should that statue of Hitler remain? Remember: Hitler was elected! He had a great deal of support!
That's a little of what it is like to be black in the US and to have to see every day those statues. I grew up in the North but I've been in parts of the south and was shocked even as a young girl at the way confederate generals were honored by street names and statues. My son was stationed at Fort Bragg and we had lots of conversations about the US penchant for naming military bases for Confederate generals and what a horrible idea that was. It sends the wrong message to white people and frankly, those statues were specifically installed to suppress black people, to remind them of slavery and that those who sought to keep them in slavery were the real heroes.
But if that is too broad for you, try this (and yeah, I know most on this board are atheist but still, I think you might get it). Again, paraphrasing from something read elsewhere:
What do you think most people would think if Christian Churches started having lots of statues and images of Satan in the church? Satan is prominently featured in the bible and is an important part of Judeo/Christian beliefs. But erecting statues of Satan might be sending a message that the Church doesn't really support.
Germany removed all those statues of Hitler and Himmler, etc. because it was the right thing to do. Statues are erected to honor heroes and leaders. Why should Confederate leaders and soldiers, who were, btw, traitors to the United States of America be honored? Revered?
