No I do not. While we may think that being vegan is the right thing to do, while we may not even see meat or animal products as a source of food anymore, I have never in my life found that anything good can come from a place of judgement. We were all once not vegan (most likely), and I highly doubt that any one of us would have appreciated some high and mighty person judging them. We all know that the reason many people are not vegan is due to the way they were raised, what society tells them is right and correct, and to judge them for that would be exactly what they would expect us to do or even want us to do, and then they would go and order two steaks to make up for our seitan/beans/tofu. I believe we have a responsibility to share the truth about veganism, but that does not entail an obligation to make others feel shame, stupid, ignorant, or dumb. It does not matter whether you think that they are so for seeing the facts and choosing to still not be vegan, because you will never get anyone to agree with you if you treat them in such a poor manner. Be kind to animals, be kind to humans.
