Nope, I haven't talked to many farmers; my family didn't do much of that and just had chickens and a small garden. The big industrial farms, even the medium sized family farms, are outside my expertise.
But I don't mind that they buy seeds every year. I don't mind that they buy GMO seeds, plant them, and sell them. Hell, I'll even eat those plants. My concern is the legal side which, unfortunately, computer science tends to get involved in more often than one likes. Patents, copyright, IP laws; none of them are consistent and companies have no reason to patent a gene if they thought they could copyright it instead and get perpetual ownership of all of the plants and all of the plants bred from those plants. Because of that, I would prefer some rational laws be laid down; not just about GMO plants but all genes and the difference between copyright and patent (algorithms/methods=patent, given implementation=copyright).
But until that happens, and as long as there is the risk that these GMO plants cross-bread and become sterile (not the terminator gene, as many above have pointed out aren't used) I will also continue to support those who explicitly do not grow GMO crops as well. And keep bringing up the parts of GMO that aren't yet well addressed.
