What's Green on the outside and Red on the inside?

I know many environmentalists who aren't socialistic in the least. They have a hard time believing me when I insist that many of their compatriots are not just "liberal" but socialist.

Years ago the Black Power movement came up with the "Oreo" cookie (black on the outside and white on the inside). Some Asian groups have a similar term: banana (yellow on the outside and white on the inside.) I would love to use the term: watermelon (green on the outside and red on the inside) however the word watermelon is, in the United States, so over-laded with racial overtones that one would spend too much time dealing with a side issue (racism) and one would never be able to focus upon the issue at hand; and that is the hijacking of the environmental issues by socialists to pursue their end of government control over the economy.
