I saw that video yesterday by coincidence. It doesn't present a complete picture of the issue.

I think it's actually attempting to ride the anti anti-gluten campaign since it's now common practice for people to take it upon themselves and bully people that don't eat gluten.

It's true a lot of idiots claim not to eat gluten, then inconvenience everyone around them, then turn around and decide to cheat or makeup an excuse and eat it anyways, to everyone's dismay.
