This. I have no concerns about my personal health when eating GMO, but the practices you describe are deeply harmful for humanity. I will avoid GMOs until sterile seeds, patented genes and the like are outlawed.
Sterile seeds are not really made/sold. Patented genes are nothing specific to GMO: varieties developed in "traditional" ways are also patented.
The reasons you cite for avoiding GMOs are really completely non-issues.
("Traditional" ways, non-GMO, mean things like induced mutagenesis: expose seeds to radiation, poisons and other carcinogens; then wait for mutations, pick a few, and cross-breed. You don't know what happened, but somehow that's supposed to be good, better than an engineered change.)
