I just want the companies to be honest about what's in the food. I may well ~choose~ to eat it given the option.
Someone said that having a tomato plant with some tuna fish genes injected into it would be no worse than just eating a tomato with some tuna fish. Fine. Great. How does that work for a vegetarian? There's a moral issue. What happens if the person is horribly allergic to tuna fish? Now there's a health issue too.
I don't a company has a right to just make that decision for someone. I'm not so happy about forced water fluoridation or iodized salt either, but at least those things are usually labeled.
