In fact, a vegan or a healthy person (who quit smoking) is experiencing internal stress, because a part inside of them wants to eat and smoke for themselves, they are trying to take it and defeat it "head-on". And as if in conversation with others, in fact, they talk to themselves, trying to explain and justify their behavior to themselves.
And where did you get the idea that they are aggressive? This is mostly shown on TV. In fact, vegetarians are far from aggressive people. Here, like bees - do not touch, do not sting. And it stings, as a rule, those who put it in vegan and vegetarian. public photos of meat))
Aggressiveness of those who do not eat products of animal or artificial origin is a myth invented by supporters of the traditional diet of a city dweller.
Often, when a patient ruins his body, doctors in a serious tone can lead you on the right path ... But it would never occur to anyone to accuse doctors of being aggressive.
Anyone who has discovered new, useful knowledge is in a hurry to share it. Warn your neighbor about a certain risk, for example. You should take it easy on this.
Vegetarians can be aggressive, boring, obsessive, preaching, they can go into their own business, they can be hypocritical, they can be snobbish, but the same is the behavior of feminists and believers, and jocks, and zozhniki, and ... who else is there? in a word, representatives of any group of people united by some common idea. You can simply hear and see those who are loudest yelling and waving their fists. And the majority of vegetarians are quite quiet guys and don't talk about their views once again.
It does not depend on the type of diet and views, but on the upbringing, cultural and intellectual level of a person. Therefore, we just have a lot of aggressive fools. Some of them are unfortunate enough to be part-time vegetarians.
It seems to me that aggressiveness in matters of belief arises from the lack of confidence in one's own rightness, from the fear of being wrong. The same principle explained the hatred of heretics in the Middle Ages: if someone believes in God differently, then I can be wrong, then I will not be saved? Fortunately, people are gradually learning to be more tolerant. Many vegetarians are completely non-aggressive, calm people who respect other people's views, but want to be treated with respect.
In addition, aggressiveness occurs if the group is small and is forced to fight with disrespect of others, with the stigma of dissidents ... I am sure that many vegetarians can tell about people who dig into them from scratch, try to feed them with meat, etc.
