What about it?   

It's on private property and has nothing to do with the government at all.   Are you suggesting we should restrict the use of their property to display statues that you don't like?

I weep for the First Amendment sometimes.

Knute Berger wrote the following about the Lenin statue in Seattle:

"To some degree, the Lenin statue is the opposite of what it appears. It could also be viewed as a trophy of Western triumphalism. It would not be here save for the fall of another icon, the Berlin Wall."

But there is even a word for the disappearance of Lenin statues across the Ukraine which used to have over 5000 of them:   "Leninopad" which translates to "Lenin fall".  It's difficult to find Lenin statues in Ukraine now but they did not erase their history.  They remember it well which is why they took down the statues of Lenin.
