I love when people post absolute FUD about a topic like it is fact.
You don't need supplements to be vegan.
You don't need to watch what you eat anymore than anyone else does being vegan.
Sorry we can agree to disagree, but on average it is a much healthier choice for most people even with the fake meat stuff.
You don't need to make "sure you get enough protein".
Just try to eat balanced meals with a little bit of protein, a little bit of carbs and a little bit of greens and you will be just fine.
At the end of the day it is a personal choice, a positive, ethical one that will change your life for the better.

You do need to watch what you eat if you become vegan or vegetarian, at least at first. Most people don't know where to get protein from sources other than meat. Most people don't know where to get iron from sources other than meat (and specially women since they need more iron than men).
The majority of people eat too much meat and not enough vegetables. Are you seriously saying that they should just remove meat from their diets and they'll be fine? No, they need to learn where to get some nutrients from other sources. What about vitamin B12 if you're a vegan? Vitamin B12 doesn't exist naturally on non-animal sources so you do need to learn where to get that.
Look, I'm all for vegetarian/vegan diets and I know first hand how healthy and satisfying they can be. But you do need to know what you're doing because it is a drastic diet change, specially for people that don't eat a lot of vegetables.
