I still don't see the connection? You don't want to take the job because it means you would be implying approval of whose behavior? That's what I don't get. Who is funding your position, the city or fed or state? What is the relation of the job to the train station, besides that they are both city property or projects? I guess I would ultimately advise, don't let other people stop you from living your life. Also, what is the quote, the only thing evil needs to succeed, is for good people to do nothing? But you are supported here, whichever way you go.
