violently disagree with this to have their say you are going to get this kind of reaction. reporter: the online bigotry has sparked an outpouring of support for the cherrio s ad. one fan posted to the cereal makers facebook page. i cannot believe the amount of racist feedback. pretty sad for 2013. another wrote, thanks cherrios for showing america the most important ingredient is love. a biracial law student said it may not be all bad. what i appreciate about the backlash, it brings to the surface things we thought were dead and gone. they really are not. reporter: may seem crazy to discuss the commercial, but that is because american companies are behind in reflecting today s society and their advertising. i think that this ad kind of opens the floodgates for advertisers to show more of the very, varied, fabric of american society. reporter: linzie janis, abc news, new york.
