Cancer vs Starvation?

Once again I got into a debate on Facebook, with strangers.  It was about GMOs and Glyphosate or Roundup.  Apparently they have found, someone has found that it is linked to cancer.  I told them I don't care.  I told them that organic total farming was linked directly with starvation and that until they could prove otherwise, it did not matter if they discovered a link to cancer.  Moreover, if they found that fifty percent of all people who ate foods that Roundup was used on after fifty years, it would still be better than two to four billion people starving to death.  It is not fifty percent of all people getting cancer.  Not even close.  

GMO food crops produce more nutrition per given area than purely organic food crops.  They produce more food that people will eat.  Granted I know people who see a black dot on a banana and conclude it is time to throw it out, green is the new ripe.  Would these people eat an apple with a worm hole in it?  Corn with a few kernels eaten out?  Hell will they eat a carrot that is bent?  Forked?  I love mutant veggies and will pick them out for their oddness, like grown together mushrooms, but they are not very presentable on the dinner plate, not perfect, but are perfectly nutritious. 

Sorry slight delay, was accused of buying into propaganda that organic food has lower yields.  I had to do a google search.  It took me a couple seconds and then I had to read the article, it was a survey of a hundred or so research papers that came to the conclusion that organic yields were 20% lower than conventional farming practices.  I did not even use GMO in the search perameters either.  

What they say is that no body is going to change anyone's mind on any subject.  With every proof of information that is irrefutable, true believers will just double down and knuckle under and hold fast to their beliefs.  You can't change their ideas because they are emotionally linked.  There is a way to change their minds and it involves presenting information that can substitute their own which a proper rational explanation.  Give them more information and hope that the seeds take root.  But it is usually a lost cause.  

I admit that I am emotionally involved too.  When they insult my arguments, by blood boils, but they typically don't attack my arguments; they attack my character.  So, I admit that I find it hard to talk with them.  They tell me that I must work for Monsanto, because I defend them so much.  I would love to work for Monsanto, hopefully they would pay me more.  I could have more time to pursue my interests, shower my girlfriend with more attention, because we all need a hobby.
