Film in foreign language

I would like to ask why should be wrong that the kids look a cartoon in a foreign language.
In Malaysia a young couple with two school girls invited me for dinner. After eating, we chatted while the girls were looking at a DVD - a fairy tale in English. I was impressed, because the father is Chinese, the mother Malay, and the girls perfectly trilingual. I thought that those kids will be the next generation in power.

Disagreement on a movie

I would like to ask how is it possible that people get so upset for a movie. I just can not find any explanation or any logical flow of thoughts, why people should burn down an embassy as a reaction to a movie which contains a message or some sentences they do not agree with.
