I am a vegan, do you know what that entails? 
I used to be a vegan for a while, but got back to eating meat, a vegan is a person who doesn't eat meat, nor any animal products.
Just thought I would ask because not many people know what it is all about. Well I too am one, a "dietary vegan" as we are called.
I never heard of this term, I respect other people's food choices. I think everyone has the right to choose, as long as they don't try to change other people's beliefs.
I totally agree!
Vegans usually try to be very healthy and I like it, it's important to take care of ones health.
And I like that there are "ethical vegans" which applies to those who not only follow a vegan diet but extend the philosophy into other areas of their lives, and oppose the use of animals for any purpose.
That's respectable, I admire how they follow their life philosophy, at least they are consistent.
It is admirable! 
I think so too! Sometimes vegan or vegetarian diet can be a religious practice as well, like in India.
