1) I have read Guillame's study before. My response, which does address several of the points his study raises demonstrates that. My point about the high price of GE seed, while not a matter that his report discusses is relevant - not because he addresses it but because he does not address it.
I did not address the issue of "agrarian distress" because we were discussing farmer suicides which is a more limited issue than the more general "agrarian distress" that Guillame discusses
2) No problem.
3) The report is clear that the results on yield (which is what we were discussing) has been mixed (see report quote below) and I've noted that some GE crops (specifically bt crops) have resulted in less use of insecticides. However, they come with a new set of issues such as creating bt-resistance in pests.
One time increases of 1.7% to 2.1% do not sound impressive to me, particularly when you consider they're comparing two groups of crops grown using conventional practices and not comparing them to non-conventional techniques. Selective breeding, hybridization, and other non-GE techniques have been producing gains in yields year after year for decades and have a record of success that stretches back centuries.
4) While avoiding GMO's is certainly a consideration for some, the main motivation to buy organic is to avoid produce grown with chemical fertilizers, insecticides, etc
5) About profit -

6) Your last link refers to bt crops which, as I already stated, do lead to decrease use of insecticides. That is a good thing, but there are problems associated with bt crops and more importantly, NO INSECTICIDE USE is better than less insecticide use. Organic farming uses no chemical insecticides. And yes, I realize bt is not a chemical insecticide and is considered organic but when applied to crops, bt degrades within a week giving the pest too little time to develop resistance while bt proteins are constantly present in crops that have been genetically engineered to include a "bt gene" which makes it possible for pest to develop resistance.
