It's a shame the word "anti-semitic" has been rendered virtually meaningless lately. It used to mean something about hating or discriminating against Jews.
Which in itself is a shame because being Jewish, on it's own, doesn't make one Semitic, and the Hebrew people aren't the only Semitic peoples who get hated and discriminated against. But don't tell an Israeli that. You'll be called anti-semitic.
The link you provided was to a description of a farmer getting sued for intentionally selecting the modified crops and replanting them to take advantage of the patented improvements.
It wasn't 'his normal crops' at all.
He was saving seeds produced by *his* plants. Monsanto couldn't control their crop and things cross-pollinated? Tough shit for Monsanto. It was his crop that was contaminated by theirs. He has every right to continue using the seeds. As for 'patented improvements', that's a load of horseshit too. They didn't invent anything. That's like design patents, a whole truckload of horseshit.
