...or allow buildings to be named after Thomas Jefferson?

That's a tough one that I'm not going to answer off the cuff.

I don't think so. Jefferson was an architect of our nation. There might not have been a USA without Jefferson. That significant a figure in anyone's history needs to be remembered. Just don't white-wash (no pun intended) over the warts. He was a remarkable man, but still a human being subject to human frailties and the realities of the time in which he lived.

It's not really a close call for me. I know what he did, both good and bad. Depicting him as some noble figure in 3/4 profile, looking slightly upward, in front of a waving American flag is the stuff of jingoism. But sweeping him under the rug is arguably worse.

And while statues weren't mentioned, I'll mention them. The victors get the statues. Saddam had a lot of statues, which were all torn down when his regime collapsed. Same with Hitler. Same with the Confederates (Jefferson Davis, etc). Defeated nations generally don't get to keep their statues.
