That guy was really funny, @rok-sivante! :) Thanks for sharing!

I personally follow a vegetarian diet for several years. And I also confess that a few years ago I was like this guy. Of course I was not as aggressive on the outer level, but inside, perhaps it was so. But at some point I realized that food is not the main thing.

If a person belives that he can become happy only through vegetarianism or organic food, he will be afraid of those who adhere to another diets. Because they threaten his happiness, as it seems to him. It is a fairly simple law of psychology. People are always afraid of losing the source of their happiness, so they always protect it. And if a man believes that the secret of his happiness is in organic food, he will be afraid of those who are against this diet. And this fear will push him to attack on them. This is the mechanism of any fanaticism. At least I see it that way.
