And you have the time, space, and labor to do this. Not everyone does. This doesn't make the food you grow significantly better than the food other people buy in the store. And it doesn't mean those other parents are poisoning their kids by feeding them gmo foods.
I don't have a problem with people deciding that they want to plant their own cotton, pick it, spin it, weave it, dye it, and cut their own clothes from the cloth. Just don't make it more difficult for me to buy (or afford) the mass-produced jeans and sweaters I wear.
Sadly, we won't have a really good grasp on what all the GMO food, antibiotics and growth hormones in meat and milk, or other questionable practices to make animals and plants grow bigger faster will do for several more years. Even then, if the resultant health issues are as bad as most of us suspect, the large corporations will have found a way to isolate themselves from financial liability.
Those guys are rich for a reason......
"Several more years"??? The technologies you list - rBSH for dairy cows, growth hormones for beef cattle, GMO insulin for diabetics - we've been using those, and eating those, for decades! No kids running around with fingers growing out of the tops of their heads, no purple-eyed calves or three-legged chickens (not that any one in the USA actually uses hormones in chickens) to be found.
We do have health issues in the USA, from eating too much and not exercising enough. But that's the same problem a few rich people had in the middle ages, when most people starved and there was not an hormone or chemical fertilizer to be found. We're just well enough off as a society that even our poor people have more than enough to eat, fancy clothes to wear, and music to listen to as they dine, played by invisible musicians.
Of course, there are still people who think the government is controlling our minds through am radio waves...
