I consider myself moderately evangelical and I now consider myself dumber for having heard that report.
I believe that there are demons attacking us, but it is the empty calories in a Snickers bar - NOT Satan - that present the danger in candy.
Traditions like Devil's night in Detroit raising the crime rate is a problem...people inspired by horror flicks to do stupid **** because they can't separate fantasy from reality is a problem...M&Ms and Nerds, not so much.
I couldn't bring myself to finish watching the video, but it seems that Mr. Robertson would be familiar with what the bible speaks regarding food offered to Idols..
I Corinthians 8:8 "But food will not commend us to God; we are neither worsened if we do not eat, nor better if we do eat it."
