There was a lot of irony and disagreement this weekend about the role that Exxon (and Forest City Ratner) played as sponsors of the Go Green Greenpoint Earth Day event in McCarren Park. Exxon is responsible for the monstrous oil spill under Greenpoint along Newtown Creek, less than one-third of which has been cleaned up after a half-century. There is a bit of a protest campaign and there was a protest and suggestions that making a fuss about it was inappropriate.
