The first is an American TV spot for cheerios, showing a nice family talking about the benefits of cheerios for the heart. The "problem" here apparently is that the commercial is showing a interracial family. This fact alone started a wave of bigot comments and remarks.
The second is an Israeli spot for a chocolate filled cereal, showing a baby surrounded by models acting in a sexual and provocative manor. In this case too the comments and reviews were not late to come. Only in this case I believe they were justified.
