One generation judges someone as important enough to them, and their contributions to society meaningful enough, to erect a memorial to them... but a later generation chooses to remove the memorial in the name of political correctness.. and seems not to understand that the next generation may see things very differently and therefore remove this generations memorials. And the end result may be - no lasting memorials and a part of history redacted, devalued, demeaned and destroyed. To the point that we are a nation with no heritage that we can be proud of.
How about this. We should leave all memorials as erected. If for nothing else a history of where we have been, what we have believed, and which roads we have walked down through the years.
If you choose to be politically correct, just remember that the last generation had a different viewpoint of political correctness; and so will the next generation. Think this through.
Will the fact, the carnage, the course or the end result of the War Between the States be changed by the removal of memorials or flags?
This time in the history of the United States is a historical fact, and no attempt to enforce political correctness will ever change it. This all happened long ago. Let it rest and move on.
No modern protest can remove the stripes from the back of a plantation slave, nor can any flag remove the death bullet from the chest of a dying Confederate soldier. Learn from it all, then lay it aside and move forward.
