I mean, think about it - if the world is overpopulated, if we produce too many carbon emissions per person, if we just suck, aren't they themselves part of the problem, according to their own logic?
Take the case of James Jay Lee, for example. Who is that, you ask? You might know of him better as the guy who tried to hijack the Discovery Channel headquarters just outside DC recently. Like all crazies, he had his own manifesto, snippet and more after the fold:
Humans are the most destructive, filthy, pollutive creatures around and are wrecking what's left of the planet with their false morals and breeding culture.
For every human born, ACRES of wildlife forests must be turned into farmland in order to feed that new addition over the course of 60 to 100 YEARS of that new human's lifespan! THIS IS AT THE EXPENSE OF THE FOREST CREATURES!!!! All human procreation and farming must cease!
It is the responsiblity of everyone to preserve the planet they live on by not breeding any more children who will continue their filthy practices. Children represent FUTURE catastrophic pollution whereas their parents are current pollution. NO MORE BABIES! Population growth is a real crisis. Even one child born in the US will use 30 to a thousand times more resources than a Third World child. It's like a couple are having 30 babies even though it's just one! If the US goes in this direction maybe other countries will too!
Now the guy's ethnicity was Chinese, a nation widely recognized as having a draconian and scarily eugenic birth control policy, but that's peanuts compared to this guy's solution - the deliberate and voluntary extinction of the human race.
Whilst most rational people can see just how frakking insane the guy's ideas are, the problem is there are too many who are equally as crazy.
Which is where the hypocrisy kicks in - They want everyone else to shoulder the blame for things - none of them sees that by their own logic they're part of the spurious problem they think exists.
They're like the eco-terrorism group ALF, which drives to their arson attacks on car dealerships, or the "animals have more rights than people" groups like SHAC or PETA who want animal testing to end, while perfectly happy to use the medicines produced as a result of such testing to date.
To paraphrase Heinlein, the problem with zealots isn't that they're willing to be killed for their cause, it's that they're willing for you to be killed for their cause.
So, why is it that in all cases of groups that think humans are the problem, they refuse to make the connection and see they themselves are part of this problem they've defined, and simply remove themselves?
