I think all “organic” gardeners should just be called gardeners and all gardening forums should by default just be considered “organic”. Those who wish to deviate from the way gardening has been done from the beginning of time should have the special designation.
On the one hand what you say makes a sort of sense, but on the other hand, if every human endeavor is only valid and true if done just as in "since the beginning of time" we'd still be foraging for wild greens, lighting fires with flints or by lightning, dying at 35 and we would not have invented the wheel (and transportation, and the internet, and the written language....!) The mere fact you are able to type your post on a computer and reach people all over the globe in seconds has a whole lot to do with synthetic chemicals (transportation/fuel and technology, all of which involve heavy use of synthetic chemicals and processes) and all sorts of other advances. And, granted, negative as well as positive consequenses; it's a balancing act.
But truly, if you are anti-synthetic chemicals and modern technology and want to be in harmony with your beliefs, why do you even own a computer? Or a car? Or rely on the grid? Or own or utilize anything that has to be manufactured or shipped anywhere? Because none of this would be possible without the worldwide petrochemical complex and synthetic chemicals, truly.
Personally, I enjoy modern life and this current conversation which would be impossible if we were still communicating without written language, let alone the world-wide grid. I do my own little best to reduce my carbon footprint where I can, and actually very, very rarely employ the use of commercial products in my garden, but let's get realistic here. If you own a computer, are on the grid, and ever purchase anything that was not produced locally (and I am guessing this includes whatever device you are using to browse the internet), shop anywhere, ever, (you never shop at grocery stores?) then you are part of, and benefiting from, the petrochemical complex and synthetic chemicals and all of that.
Doesn't mean you are not a "normal" or "non-organic" human.

But the very fact that you are posting here is evidence you are as much of the complex as we all are, so I don't see how cherry-picking non-organic gardening as teh evil advances any sort of cause. If you don't want to use commercial applications, then don't. I would totally respect the integrity of someone who lives off the grid and sincerely believes that do do otherwise is wrong - and I'm an old hippie kid, and lived exactly that way for many years, no running water or plumbing or electricity or heat and quite frankly I wouldn't want to go back there ever - but someone on the grid berating other? Not so much.
