Sorry the first and last sentences seem most appropriate for an answer.
The greenies aren't the ones who pushed for NAFTA & GATT. That was the globalists. The greenies just reaped so many benefits it's easy to look past the darkness of the NWO/NAU and see the glaring nuttiness of the greens and blame them, because the reality of the other is too horrible to contemplate.
You say they regulated manufacturing to the point it was driven offshore. Do you really think this lonely splinter group has such power on their own? I'll bet the number of really hard core greens numbers well less than a million. Takes a lot more than those kind of tiny numbers to make a dent in federal regulations! Especially in the fairly short time periods here. The greenies have some serious horsepower backing them. The kind of power that's spelled C.F.R. and Bilderberg.
The greenies aren't the head of the snake. They're the lackys of the globalists. In this New World Order they are rapidly creating, all mainstream religion will be pushed out or crushed. The new religion is going to be the greenies. Eventually (sooner rather than later in my estimation now) when the antichrist takes power, HE will claim to be the creator of the greens (and everything else) so he will become the focal point for the movement and NO I don't think the antichrist is Obama.
Lonely splinter group? Are you kidding? The greenies are a collection of every far left splinter group behind one issue that they chose to demagogue because it had the capability to put people on an emotional guilt trip that nothing else did. The Democrat Party and the greenies are one and the same. The only element that the Democrat elite missed was that most of their efforts were in conflict with the blue collar union voters. So, they had Obama saying one thing and his commerce adviser (Goolsby) saying the opposite. So, the union voters could believe Obama was supporting them (they were right) and the limosine liberals could believe what Goolsby said.
As for not having power, it’s not the Greenies who have the power, it’s the politicians using the Green movement for cover. I’ve seen it, up close and personal in my own county. The greenies drove out the manufacturing jobs and made the statement that the workers will just have to move else where to find a job. I’m not kidding, that was their reaction, as printed in the newspaper.
