If I were Mr.Brownell I would cut off my funding of community projects immediately. See how long what sounds like an economic stranglehold would take to change the communities attitude.
170 people sign a letter and fewer than that whine about it publically. This is in a town of 10,000.
I'd say ignore the whiners...and keep ignoring them. I would be loathe to cut off the town because of a few malcontents. If these "activists" don't like his money they can continue resigning from organizations that take his money or, if they control the organizations, reject his money at which point, we has the bigger man and has no further obligation with that organization.
I somehow think that there are plenty of organizations who will take his money while a few that probably need to go away won't.
So be it. Pete can be the adult.
