I get this sentiment, but you're kind of saying this like "the town" is some singular entity, or one person, who's now flip-flopping or being hypocritical. It's not. Those were completely different people who made that bad decision 50 years ago. People in Arlington today aren't the ones "responsible" for blocking the red line, and they might reasonably feel like they got screwed over by those decisions made by people two generations ago. Yeah, I think Arlington "deserves" better public transit, just like every other city and town around here.
