I have been vegetarian/vegan since I was child. So I will say its been roughly 14 years or more. It was a personal choice and mostly because my mother was a health nut hippie and I wanted to be healthy since I was chubby as a child. My father was a hunter so I’m used the fact that animals are killed for meat. However it never bothered me. I mean I don’t want any but I always just said “no thank you”. Choosing to eat a certain way is the same thing as choosing not to drink (which I also don’t do). To sit here and complain about people eating meat is just childish. It’s like your vegetarian for attention. Be polite. More people will respect your decision of you respect there’s.
