No, I'm not saying that, and you're ignoring my many posts where I explain my position to come to this conclusion.
You're not saying what I quoted verbatim, and I'm ignoring your posts where you explain your position to come to this conclusion? I can't really parse that. But you did say, "We don't have natural selection at all anymore in terms of what parts of the earth humans are dominant." I think we still have natural selection all over the place. Whatever.
No joke....
Wait so now you're agreeing with me?
I agree with the obvious truism that humans influence the environment (probably more so than any other species), which in turn influences selective pressures that bear on other species. So yes, of course. But that doesn't mean "we don't have natural selection anymore, in terms of..." anything!
I don't think anyone who is really concerned for the environment would take that position as you've presented it. But there's sound reason to be cautious, even downright alarmed, about letting "humanity's designs" out into "nature." The following example is deliberately cartoonish but will do.
Again, let's take an ecosystem consisting of cheetahs and gazelles. Both are very fast, and they got that way by co-evolving in what Dawkins refers to as an "arms race." Rewind the clock to Flinstones Time. Flintstones cheetahs had to be only so fast, because the Flintstones gazelles were only so fast. But still, some were faster than others, and a little extra speed conferred a decided reproductive advantage on the faster gazelles, the upper end of the bell curve. So after some generations, the norm for gazelles was faster. And so in turn the genes for slower cheetahs came to a dead end, and cheetahs got faster on average. And so on, over many generations, until we have these very special cats that can sprint at 70 mph, and gazelles that are, I don't know, fast. All this took a very long time.
Now imagine that Genes-R-Us comes along and engineers a super-cheetah, for some perverse reason, like winning in the high-stakes world of cheetah racing. Or something. These cheetahs can go 90 mph. And some of them get out into wild breeding populations and start passing their badass genes on to their offspring, who naturally enjoy this competitive advantage to the fullest extent possible. What we have is a sudden jump in the capabilies of cheetahs.
Now what do you suppose happens to the gazelles? The population co-evolved alongside 70 mph cheetahs. It can't cope with 90 mph cheetahs.
Very soon, the cheetah population goes way up, and the gazelle population goes way down. Then the last gazelle is eaten, and the cheetah population goes way down. And bang, like that, the cheetah-gazelle axis is gone from the world. This is what biologists mean when they get all poetic about the delicate web of nature.
Again, the super-cheetah is a silly example, but not at all far-fetched. It's the same complaint we hear about super-salmon, just simplified. And it's really not much different from other kinds of invasive species problems. So GMOs aren't necessarily singled out here. Anyway, if you're asking how artificial selection is different from natural selection, there's your answer.

Here's an example of you taking me literally to argue a point thaty doesn't matter. I think you can assume I meant the society that is humanity, a meta-society, unless you are just being argumentative.
I'm not. I have a BS and a Master's in the social sciences, and have taught graduate courses, and am unfamiliar with the concept of a meta-society composed of all humanity. I'd be glad to hear more about the theory of the meta-society.

My point (once again) is that you could argue humans supporting their own kind with physical flaws ("breeds" of man which "nature" wouldn't intend to live) is analagous in my mind to humans supporting and creating food crops that wouldn't otherwise flourish.
I guess you could argue that, but I don't see anything in it. Breeds of man that nature wouldn't intend to live? If you're saying that's bogus language and bogus reasoning, I couldn't agree more.
Well, no kidding. If nature didn't want us to have rifles, she wouldn't have given us Mr. Winchester. This doesn't mean we have to massacre the buffalo.
There's a specific reason I asked "fit for what." If you knew what Darwin meant by that phrase you're tossing around, you'd understand that.
Sure. This is not to say we've fixed damage we wrought on the ecological equilibrium! Dang ol' Band-Aid on cancer, man.
Exactly. We've hosed the equilibrium to the point that deer have no natural predators and have become pests, like rats, that we have to go exterminate. Tell me how we're restoring that there equilibrium, MakK.
So now they're just less polluted. Which is fixing the ecological equilibrium. So I guess that means the current extinction rate should have reversed itself and headed toward background extinction rates. Oops! Wrong! It's still 2-3 orders of magnitude higher.
Again, I haven't noticed our ability to fix ecosystems we've fucked up.

A charming view of Darwin's work, and of the natural world in general.
