Wow such confidence. Too bad your understanding is lacking. Arlington is indeed not such a bad area. But folks in Arlington and Lexington (the planned terminus for the red line) were the ones that objected to the expansion. They didn't want increased traffic (all the people trying to park to take the train would make their towns less quaint and all), and they didn't want the urbans/poors/etc to be able to easily visit.
