No argument from me that people should generally avoid using roundup, not to mention various other chemical insecticides and herbicides. I do think there is a difference of degrees between occasional use of a liter spray bottle around the home and using it on nearly every acre of soy and corn grown in the US with the exception of organics. It also goes beyond immediate health effects to the exclusive planting of a mono culture of roundup ready crops. To me, boycotting roundup or Monsanto also implies boycotting most or all GMOs and buying organic wheat, corn, and soy products especially.
