In essence, Curtis White says that progressive charities have to be wary of being too activist, at least if they want to be very big, because progressive philanthropic organizations will kneecap charities that might get too “uppity” with their ideas.
In the end, philanthropy wants the wrong thing. It may think that it ought to want what the lovers-of-nature want, but its actions reveal that, come what may, it loves other things first: the maintenance of its privileges, the survival of its self-identity, and the stability of the social and economic systems that made it possible in the first place.
And, White just touched the tip of the iceberg. What he calls "Big Green" is more commonly known as "Gang Green," and, its donors are part of the reason why "political access" is more often the coin of the realm than is idealism.
