What do you think of vegetarians' behavior of preventing others from eating meat?

Whether it is vegetarian or carnivorous, whether it is back or meat, it is a personal food choice. It is determined by personal beliefs and personal preferences. Within the legal framework, others have no right to interfere. So I think vegetarians should not use their own ideas, beliefs, preferences and moral standards. Demanding others, accusing others, interfering with others' freedom of belief and depriving others of their right to freedom of belief. We should not judge what others have done from the so-called moral height. Self-righteous people think that vegetarianism is much more noble than eating meat. As everyone knows, plants are also alive. Vegetarians are not much more noble than meat eaters.
