Well, I dunno 'bout GM food, but from a purely personal point of view, the produce they've been pumping full of hormones and steroids for years is just nasty. When's the last time you found a great tomato or banana or something in the supermarket? Banana's for instance... they've gotten 'em to the point that they're friggin huge, but have absolutely no flavor at all, and the texture is just gross. Same with tomatoes. I swear by all that's good and holy that if I crack into another tomato and find it all white, hard, and mealy, I'm gonna freak out and start sniping produce managers from the roof of the local grocery store. Melons, apples, everything else. So what if they weigh fourteen pounds if they're inedible? Maybe I'm just too picky, (working as a chef for 10 years will do that to ya) but go out of your way sometime and find a reputable organic or home-grown stand and try some of the stuff they've got there... see if you can't tell a difference.
My point is, if stuff is this bad now, how much worse is it going to be when they start genetically modifying food?
Change is bad... I fear change....
