IMO, we should all eat what keeps us healthy and happy.
You don't feel good eating meat? Don't eat it. Just be sure you have a source of complete proteins, omega3s, zinc, calcium, vitamin b12...... Cutting animal products out of your diet is not as simple, or healthy, as you might think.
Vegan is a subset of vegetarian. Don't confuse them. If you're vegan, not only can't you eat eggs, meat, dairy, but you can't wear leather (shoes, belts, jackets or wool), go to zoos, ride horses, own pets and on and on. Vegetarians just don't eat meat.
