Then if we seek to make this change, where do such changes end?  What should constitute an issue worthy of such a change?

If we take away Deady's name from a building he had a role in providing - because we feel we are now somehow better (more righteous?  more all-knowing?) than his contemporaries who judged him worthy of the honor, there is no end to the work we must then do.

Joseph Lane's political sins were far greater and far reaching than Deady's.  Let's change the name of  our County.

Then let's go up the valley and do the same for Polk County - after all Lincoln (repeatedly) said James K. Polk lied us into the Mexican War.  Historians say that Polk wanted to satisfy the South by creating slave states in what we now call the American Southwest.  So he sent the (forerunners to ) the Marines to train their cannons on the Halls of Montezuma - the Mexican national legislature. 

Let's then give Arizona, etc. back to Mexico.
 
The list of such changes we could propose is endless.
