Do you agree with me about this?

Okay, I've come to the conclusion that vegetarians can be perfectly healthy without meat in their diet. I rarely eat red meat myself and I'm not vegetarian. If they get most of their protein from eggs, cheese and milk, they don't have to eat meat or fish and they'll be fine. Vegans are another story. If they know what they are doing, and that's a big if, they can possibly get all the nutrients they need. Now here is the problem. A lot of new vegans are teens. Most of them don't know squat about their nutritional requirements. So they start eating vegetables and fruits all day long and they think that's fine. They get next to no protein and no healthy fats in their diet. And they are still growing! Now if they studied nutrition and veganism they could possibly figure it all out and eat what they need, but how many youngsters are going to do that? For adults it's not as crucial but for a growing child, it is IMO. Without protein or healthy fats in your diet you're in big trouble and asking for health problems down the road. And this is why I'm against persuading young people to become vegan. It just seems like a dangerous thing to do.
