I'm OK with GMO products, what I hate is:

* GMO that don't produce viable seeds so I have to buy seeds from you every season.

* GMO that only works with some other supply available only from the same provider (think of a car that only works with gas from Ford).

* Patents on living organisms: a farmer should be allowed to plant the seeds they grew in their own farm, produce hybrids and so on, without paying royalties.

* If GMO strains get accidentally cross-pollinated from a neighbor farm you should not be on the hook for it.
