I have mixed feelings on the confederate statues. A case could be made for the charges you mentioned but we also need to remember that the Declaration of Independence said that when the government gets out of control we should cast it off and form a new one. Maybe not the exact wording but you know what I mean.
So a case could be made that the Confederate states were just following the founders wishes in that regard.
I guess my issue is that once those statues were placed they became a part of the landscape as piece of art too. Rather than just haul them off in the middle of the night under secrecy a public referendum should have been held and let the voters decide if they should stay or go.

In Houston in can take 8 to 10 months to get a pothole fixed in a major road that can cause damage to cars but let's not take care of that with any sense of urgency. They wasted no time jumping on the bandwagon to remove statues though and those statues posed no threat to causing damage to anyone.
I guess what I'm saying is that there needs to be some prioritization when doing things and knee jerk reactions to certain peoples wishes shouldn't vault them to priority status.

That "don't be surprised" mention isn't without some merit to it; a family friend who's son is in the army said he is being deployed to there as part of that 30,000. I don't have the exact date of when he ships out, I'll see if the wife can find out.
