Even if everyone reading this article went vegan immediately, it would do less than if they went out to protest and told all their friends about it too.

I would disagree. Or at least, it’s not obvious or established. Protest and heart-to-hearts don’t move the needle very much at all. Our individual economic and cultural contributions simply by living as vegans are powerful, not even considering the huge number of individuals each of us directly protect from atrocity with our individual actions.
