The pipeline lobby accuses environmental groups of being funded by the US sometimes along with a nefarious plot to prevent Canada from getting a higher price for its oil. The argument carries no weight with me. I'm not going to support or reject pipelines based on who is paying environmentalists.
I think most people feel the same about PR. Just give us the facts.
Magoo is more devil's advocate than troll. He identifies weaknesses and false logic in arguments.
It can be very annoying especially when he doesn't seem to care either way but there is an upside. It identifies weak points in the arguments so they can be avoided or solved.
Who's paying can indicate some bias but it doesn't invalidate an argument or a study.
