If we only had statues of perfect people we would have no statues. These people aren't saints, they are interesting people who lived interesting moments in history. If we huddled up every statue and removed them because they did something wrong in their lifetimes no one in modern society would have one. It might make for TV clips you can enjoy, but all you're left with is a society that doesn't even remember what life was like before our time. I realize this is what some people want, so I'll say this; when you face challenges today you cannot handle don't bother looking back at the history books. If one day you need to look to history to see how they handled the same exact difficulties we face today there won't be anyone to look to, by then they'll all be long gone.
