A very large significant number, and I doubt millions of millions of people would boycott them. The thought of what I meant is that people wouldn't go for it, so boycotting wouldn't be effective.
I doubt millions and millions of people wear fur in the first place, but regardless you said boycotting wouldn't work at all and it was based on a presumption, and you were probably incorrect there. I don't think it would be beneficial to argue this much further, as your point's already been made a couple of times and I've made mine, and there's not much more that can be said
To help you even more, I've put that up on my own forums to try and get my friends to sign it as well. Well, I read that and I was horrified! Omg.....
