I found vhemt.org unfunny, bleating and dim-witted. The very dogma it attacks is on the basis of another dogma, almost entirely composed out of the naturalistic fallacy and appeal to nature. YMMV.
I certainly agree that they take it too far. I don't see what's so great about a planet with no people, and how it is it better than what we have now.
What I do find interesting, is the idea that having a child can be seen in an environmental and altruistic light. For me, it was a new thought that not having kids might be a good choice for myself, my girlfriend and the world in general.
An empty world would be a horribly sad thing, but perhaps a billion fewer people would make the world better for the remaining six billion. (And for the record, I'm talking about voluntarily getting fewer, not any forced methods)
