I myself really don't care about most of the monuments that are specifically about the confederacy, especially the ones that depict Robert E Lee and Jefferson Davis. Especially the ones that are here in Tx.
Of course, there are many more monuments that are about the confederacy or have confederates in them such as the one of Lawrence Sullivan Ross at A&M. Wanting to tear down a monument just because a person fought in the confederacy is a little far IMO. People are flawed, and most people back then were racist.
It makes me wonder if in the future our descendants will be ashamed of each one of us posting because we used ICE (Internal Combustion Engine) vehicles. Or, *gasp*, we participated in activities like boating or went on cruises that have especially high emissions and pollution. You don't even have to leave a diary or letters like in the old days, nowadays it's all on the internet or stored somewhere digitally. We documented our own crimes, with pictures and video on social media. Even this site may be stored somewhere 100 + years from now.
Or we used plastic products, or worse, worked for a company that makes lots and lots of plastic like myself. So, should I be lucky enough to get a statue built in my honor (unlikely) 50+ years from now will said statue then be torn down 150+ years later once they realize that I burned fuel, used plastic straws, and worked in the very industry that created all the pollution in the first place even though it was perfectly acceptable and normal at the time I did such things?
After all, there are people right now living as green as they can, riding their bike, walking, using non-plastic items, bagging their own groceries with reusable bags, taking public transportation, etc and encouraging everyone else to do the same. But just like in the old days, there are always people advocating for the abolition of slavery, equal rights, etc but most people just accepted the norm until the norm was changed either by war or some other external mechanism.
