Is Vegan a Brand?

Good day to you.  I am hoping to get feedback on this question, because it just today occurred to me to ask it.  I was reading the new issue of Adbusters, issue 76, I think, and it’s all about brands.

I am against branding, and try to avoid branding myself where possible.  I do brand myself with antiauthoritarian tshirts sometimes and with my school logo, but I try to keep it to that. 

What about Vegan?  Is it a brand or not?
