they make plants that produce chemicals to kill pests, with possibly unknown health effects (although at this point these effects have been studied pretty thoroughly)
The effects and method of action of BT genes and their subsequent Cry proteins are well known, understood, and regularly used even in organic agriculture. All plants naturally produce their own chemicals/pesticides, otherwise pests would just be eating the shit out of them and they'd go extinct. Adding one more already naturally occurring pesticide that is demonstrably unharmful to humans is really no sweat.
they make plants that are resistant to herbicides, which promotes the use of these herbicides, which promotes the development of superweeds
Herbicides such as glyphosate were in use long before genetic technology came along, and for good reason: it's relatively benign compared to other more harsh and toxic herbicides that it replaced, and it was much more successful because it was broad spectrum and could kill a wide variety of pest plants rather than having to use two or three different herbicides to accomplish the same. It's for all these reasons that it was chosen as the target for resistance engineering, not the other way around. The idea of "superweeds" is a little ridiculous because at worst, weeds become resistant to glyphosate and we're simply right back where we started before. It's not like these weeds are suddenly going to be super hardy and resistant to everything and begin taking over the world. They'll simply be resistant to glyphosate.
they patent everything and engage in licensing schemes that are really harmful to small farmers.
When you're spending hundreds of thousands to millions on R&D, you kinda want to protect your investment. Plant patents have been around a lot longer than GMO technology anyway. Farmers are falling over each other trying to buy GMO seeds, and no one is forcing them to sign contracts that they don't want to. Anyone is free to go and buy non-GMO seeds wherever they like. Farmers aren't doing this, of course, because the GMO traits allow them to get better yields with fewer inputs, thus making better profits. GMO crops hurting small farmers is laughable to the farmers using them. Unless you think farmers are stupid hicks who don't know how to math.
but merely by making it more resistant to pesticide, so that they can smother it,
I'm sure this is a waste of time replying to an ignorant Anonymous Coward, but do you have any idea what level of spray actually hits fields on a per acre or even per square foot basis? I bet if you ran the actual numbers, you'd be dumbfounded at just how little an amount something like Roundup is required to have the desired affect. We're literally talking about oz. per acre, diluted into gallons of water. It'd be quite a stretch to call that "smothering".
Also glyphosate as a chemical is now off patent and anyone can make and sell it.
(the name escaped me at the moment)
And right now, that's absolutely the case.
Let's stop all funding and research on everything that isn't economically feasible right now!
Monsanto suicide genes
A myth. Show us where you can buy these, please.
BT soyabeans, which causes all manner of illnesses in humans and animals
Myth #2. BT toxic is completely inactive in mammalian guts due to the acidic environment and lack of appropriate receptors to latch onto. Cry proteins are digested like any others.
Maybe next time, have the first clue what you're talking about before you spout oft-repeated bullshit.
