One of the anti-GMO arguments is that you don't want to get a knock on your door (and a lawsuit) from Monsanto for accidentally having a field next to your Monsanto-loving neighbour.
Except that it's never happened, to my knowledge. Monsanto has sued farmers for using their seeds illegally, and in those cases it was shown that the farmers did so knowingly -- accidental cross-contamination has never been sued over. For instance, in one case a farmer claimed accidental cross-contamination while using Roundup on the same crops (which would've killed non-GM crops); in another, the field was found to be nearly 100% GM crops, a virtual impossibility unless seeds were explicitly and knowingly planted.
Monsanto does many things that people can take issue with (e.g. patenting seeds, which isn't reserved for GM crops, mind you), but this is pure, unadulterated bullshit.

You mean it's wrong, let's not exaggerate here. I'm just saying what I saw on a documentary featuring three farmers.
This is pure FUD and has never happened. If you are ready to stop spreading false propaganda, you can go to Wikipedia and read what really happened in those cases: http://en.wikipedia.org/wiki/Monsanto_legal_cases
In 2002, Monsanto mistakenly sued Gary Rinehart of Eagleville, Missouri for patent violation. Rinehart was not a farmer or seed dealer
which seems to contradict your claim that it has "never happened".
Let me quote a bit more:
"In 2002, Monsanto mistakenly sued Gary Rinehart of Eagleville, Missouri for patent violation. Rinehart was not a farmer or seed dealer, but sharecropped land with his brother and nephew, who were violating the patent. Monsanto dropped the lawsuit against him when it discovered the mistake."
No it does not. What /u/nodata wrote was: "...for accidentally having a field next to..." and Gary Rinehart was not sued for accidentally having his field next to whatever. He was sued for some other reason.
(Not a good reason, but other reason anyway.)
