It was a classic, flawless, airtight bit of NIMBY reasoning:
Outsiders look like nobody I know. I don't ride the Green Line. None of my friends ride the Green Line. Nobody I know rides the Green Line, ergo, anyone riding the Green Line is someone I don't know, and who is not my friend.
I had to admit, there is no refuting that, and I sympathized in a way. Also there was this quote:
This is Medford. When we need to go somewhere, we drive.
But from there, things got psychedelic:
Green Line riders were going to be so poor they were going to steal all "our" stuff, but so rich they would want to replace the hair and nail salons with Starbucks. Home prices would go up so much "our" children can't afford to live here, and go down so much that "our" life savings will be wiped out.
The Green Line is so high-voltage that it will surely electrocute people, but others noted that idling MBTA vehicles always fill neighborhoods with fumes. Vehicles are so quiet, that they hit people who didn't see them coming, and so noisy that you can't sleep at night.
It will be so empty nobody will use it and will be a waste of money, and so full that there won't be any place to park.
