The "wetlands comment" was an attempt at humour, he was just being facetious. That's how I took it. Who knows, this guy seems to have bought many of the left's lies, maybe he also thinks Bush put arsenic into his drinking water.
Agreed, he's just saying, those arguments (which by Farber's other writings he doesn't agree with) are trumped by the one overriding issue: terrorism.
The left is good at listing a string of BS together and calling fact. And the worst thing is, if they do it often enough, the simple minded voters start to believe it.
