Under the principle of "eminent domain," local, state and federal governments can force property owners to sell their land if the government decides it's in the government's (er, the "peoples") interest that they do so. In Washington, D.C., an outlying area is home to a number of gay clubs that now stand in the way of a new stadium, and the city's liberal mayor and city council are forcing club owners to get out even if it means the loss of their livlihood.
These are successful businesses operating in the one area where the government's draconian zoning laws had, to date, tolerated their existence. But apparently if you're deemed "sleazy" by the state then you're not entitled to any respect for your property rights.
First they came for the strip clubs...
