Natural Hybridization is one thing. That is still natural and the laws of nature allow it. Genetically manipulating DNA is something completely wrong... If it can’t happen naturally then it was not meant to happen and should not happen. It is playing God...

Selective breeding is the opposite of natural hybridization. It’s pushing plants in a direction WE like, that wouldn’t happen naturally. Corn only exists because people decided it should, that was a decision made 9000 years ago, but they bred for it, emphasizing traits that made it good food, but wound up with something that propagate without us. The only difference between what we do now and they did to make corn is we’ve got killer microscopes and labs to figure out what gene makes this trait happen and push it that way, they just figured cross pollination through trial and error and got lucky.
