LOLwut and RafC's answers are wonderful; that's the spirit!!!
I'm an outspoken vegan, of course.
Imagine the time when slavery was the common thing... and someone didn't "believe" in slavery, but didn't say anything, because he/she didn't want to "offend" those who wanted their slaves, because it was their "personal choice"... come on, what good would that do? It's the same with animals...
This world needs more outspoken SEERS... and when you become vegan, you become a seer in the matter of ethics. If you don't speak up for those who can't speak for themselves, then the world will never change, and abuse will continue...
As long as vegans are ashamed of themselves for being vegans, things won't change. Why being ashamed, or scared to SHOW what you KNOW, when it's the best option for everyone?
