Right on schedule the moving goalpost away from 'genetically changing a plant is bad' to 'the way I don't like is different therefore bad'. If you note, you'll see that everything I mentioned are actually all quite different. Various types of somatic and induced mutations, selective breeding, biotech facilitate wide crossing/embryo rescue, artificial chromosome alteration...very different from genetic engineering, where a single well known gene is inserted. Why not lump genetic engineering in with everything else and select the chromosomal duplication to be the pariah? After all, that is also an entirely different thing, which I don't think is particularly meaningful, but means about as much as your argument. What I personally do is both more and less extreme than transgenics, depending on how you want to view it. The lumping of everything as 'conventional breeding' to make a dichotomy between it and genetic engineering is a very simplistic view.
without the slightest idea (or any way of finding out) what the effects will be in the long term.
Fallacy number two, the straw man. Do you really think the scientific community, which overwhelmingly supports GE crops (don't even try to deny this), does not pause to consider such things? Perhaps you could explain your long term fears in less vague terms?
But that doesn't matter, does it? To those whose only reality is profit, there is no future beyond the current quarter.
Sorry, the corporate card has no bearing on scientific topics. Save it for politics.
