Well I think there's too much unnecessary drama about being a vegan or not, apparently vegans think it is not healthy that you eat meat and non-vegans think that vegans are just being too nosy about what they should or should not eat. Don't force your beliefs on what you think is the better one, if you want just provide facts or stats to show how your way might be the better one, and if the other person doesn't think that they want to change anyway, why continue nagging them?
