You should tire of it, because it isn't true. Dan Rooney was appointed ambassador, which isn't a cabinet level position. He also isn't the only owner of the team. Or are you actually on Team-0 yourself? They seem to be making up crap just about every day.
The Steelers aren't owned exclusively by Dan Ronney. About half of the ownership is conservative, including a Rooney who's a Florida Congressman [Tom Rooney, lifetime ACU 88% -- the same as Alan West.]
Many of the players were unhappy with Rooney's idiotic endorsement of Zero, as were most Steeler fans. His father, an observant and staunch Roman Catholic is spinning like a lathe in his grave.
The base Steeler Nation isn't just in still heavily Democrat Allegheny County; it's also in conservative Central PA, conservative Eastern OH, and conservative West VA.
Get a clue.
