To blend all those different techniques under the same term would be useless and confusing to both science and consumers.
That's true if most mutations produced through and then artificially selected for in modern mutagenesis based techniques, as well as most of the mutations irrelevant to the targeted trait that come along for the ride.

3,000 years isn’t all that long and we don’t know that, what we do know is that no mutation that does that has occurred where it has been in net of cost to the organism useful enough to be selected for an retained, which is a very different thing.

So? The post you respond to acknowledges that they are different but notes “it is insane that mutagenesis (especially in its modern forms) is not treated as even a moderate concern by the same people who hold up transgenics as an existential threat.”
That it is comparatively easy to do a precise, targeted change where you know exactly what new thing will be expressed and change little else through transgenics isn’t in dispute, its the whole reason for that statement.
Some not. We share common mechanisms with other life beings, but most of the time, Yes, they are. You will not find a single animal able to photosynthesize by its own means.
> mutagenesis can produce genes that don’t even exist in nature
Because they are broken. DNA "per se" is useless unless it can be read and used to build something useful. Mutated genes are like changing a paragraph from a book to a language that does not exist and can't be translated. Most of the times the result will not made any sense. Evolution will eventually clean the mess, as usual.
Genes aren’t inherently kingdom specific, and mutagenesis can produce genes that don’t even exist in nature; moreover, it produces changes all over the genome; when you then select for a desired trait, you still have unrelated changes all over, whereas there is a whole lot more control and knowledge of what you have with transgenics.
Yeah, they are different techniques, but it is insane that mutagenesis (especially in its modern forms) is not treated as even a moderate concern by the same people who hold up transgenics as an existential threat.
