Huh? From your own link

• organic farmers use different kinds of pesticide if they use pesticide
• they need to use non-pesticide methods first, and any pesticide use is heavily regulated
• while some of the organic and limited synthetic pesticides could and do have potential human health implications, the vast majority of the synthetic pesticides used on conventional produce are widely recognized as probably having some damaging impacts on humans eating produce contaminated by them.

As a result

• Conventional vegetables were contaminated with 2 to 17 times as many pesticides as were organic vegetables. Conventional fruits were contaminated with 6–75 times as many pesticides as organic fruits.
• The dietary risk index was more than 50 times higher for conventional vegetables than for organic vegetables, and more than 130 times higher for conventional fruits.

Don't both sides this. The person saying buying organic is just raising your grocery bill without changing your pesticide exposure or risks is objectively, factually wrong.
