You haven't done the research. Get online and do it. You criticize and provide nothing but your own opinion with zero science to support it.
Here's a start to becoming informed on GMO harm:
http://www.rense.com/general80/haz.htm

If there was nothing wrong with GMOs then Monsanto wouldn't need to buy congressmen to pass a law that prevents anyone from sueing Monsanto for damages from GMOs.
Monsanto KNOWS they are harmful, KNOWS they infiltrate non GMO crops because they designed them to do exactly that.

A quick google on your part would have shown you all you asked for, but I did some for you so others can see it, too.

Monsanto sues farmers for growing GMO crops without buying GMO seeds when the crops have been genetically contaminated by nearby crops using GMO seed. They want to force farmers out of business or force them to use GMO seeds to expand their business. Their hoped-for-monopoly is being protected by looters in goverment.

Monsanto are evil bastards that make Ayn Rand's villains look like choirboys in comparison.
The court assumes that Monsanto's science is perfect until innocent farmers spend a fortune on lawyers, and even then the court gives the advantage to Monsanto. This is about bad science and corruption interfering with justice.

And the proof of the 'harmfulness' can be found where, other than in your assertions to that effect?

and, pray tell, if GMOs 'infiltrate' non-GMO crops, where is the business case that would explain why Monsanto would even want to DO that? They want to keep their seeds proprietary. If they easily cross-bred with non-GMO crops, their profits would be diminished. Your logic, please, if possible?

yeah, like the nasty GMO'd rice that contains high levels of vitamin E and prevents blindness?

Yep, sure want YOU on that team.... [not.]

NO, THEY'RE NOT. The seeds have been genetically modified so that they are RESISTANT to Roundup, so that Roundup can be used around them as the crops are growing, so that weeds don't compete with the cash crops for water and soil nutrients.

Your lack of scientific knowledge is typical of folks who believe all the anti-GMO crap on the internet but have not taken any good biology, chemistry or general science courses... or passed them.

The shit about mice dying from being stuffed full of GMO seeds is also Bad Science. Those are SEEDS used to grow cash crop plants. You don't eat them any more than you go to the grocery store and buy a bag of SEED CORN for your next soup.

THAT kind of rational thinking is completely missing from your 'arguments.' It's just a real shame that so many people can't handle the thought processes needed to refute the stupid Bad Science claims of the Anti-GMO Zealots.

I don't understand the science, but my very crude understanding is GMOs aren't dangerous.

GMO's are genetically modified organisms. These are the crops that have Roundup herbicide in them and can damage your DNA so you become a permanent poison factory. Almost all corn and soy are GMO. The crops that have Bt, another insecticide, sliced into the DNA cause holes in the intestines in the form of leaky gut syndrome in people and blow out the digestive tracks in the bugs. There's a lot of propaganda out there by Monsanto and other biotechs.
