I don't see the problem with designating a historical building....
From the article:
the Pullman Historic District in Chicago was the country’s first planned industrial town. It become well-known after a violent factory strike in 1894, which came to be seen as a pivotal moment in the history of the labor and civil rights movements for leading to the creation of the first African American labor union.
Oh, sorry. Am I supposed to be outraged because Obama? Woops.
