The vitamins thing isn't strictly true actually, some vegetarians have really specific diets where they get the vitamins from other foods, but they're usually rich and can afford all that quinoa and shit
I have plenty of friends who've eaten fake meat products and preferred it to the "real deal." In fact, once it was the deciding factor in my friend making the transition to being a veggie.
but I don't agree with having to have it in order to give your body the right nutrients. if u need to do that then obviously you're not supposed to be vegetarian.
I disagree with the meat trade, it's inhumane and I don't want to be a part of a culture that doesn't understand respect for life or the concept of finite resources (it's been proven that humans eat way too much meat). When I'm older, I may buy meat from a trusted source i.e. a butchers, because I know it has been sourced properly and is sustainable. I don't mind something dying for my pleasure to eat — that's always happened, but I don't see why something should suffer for the same end.
I could explain further, but I end up having to double back on myself to explain things and link things up and the like.
So as you can see, vegetarianism is not stupid, it is in fact a social, moral, political and philosophical ideology that stems from many intellectual places
Like if someone was on a diet where they needed a milkshake to provide their body with the stuff they needed. Then you shouldn't be on that diet cause it's bullshit.
And generally, I'm a lot healthier than most people who eat meat, anyway. Meat isn't supposed to be eaten with every meal — it's more damaging to eat it all the time than not at all
It's not a good idea to get me started on vegetarianism least of all because I'm not strictly a vegetarian, I don't like sticking to a term, having that dictate my eating habits. Sometimes I eat meat, i.e. a special occasion, or if I literally have no choice
Like I say, I'm fine with the animals dying. I just don't want to be a part of their prolonged suffering is all. Besides, if everybody in the world became a vegetarian (which far too many vegetarians think they should), what'd we do with all the animals? They'd lose purpose... we'd have to kill them all, essentially, because otherwise they'd just be taking up space.
A lot of veggies are very self-righteous and think they know it all, I'm not one of them. I have dissuaded people from becoming vegetarian at uni because, simply, it wouldn't be the best option for someone with little money.
I just see it as a general personal trait more than a strict dogma or anything.
