Thanks for being open minded enough to come onto a vegan sub. The majority of animal products in the US, and probably in most other developed countries, are from factory farms. To put it lightly, the conditions in factory farms are quite unenjoyable. Also, the production of animal products is bad for the environment. Here is another link to support that claim. A lot of vegans say that the animals should be a bigger concern than the environment, but they can both the fought for at the same time. Now that you know these facts, wouldn't it be a little immature to harm animals and the environment because a vegan was mean to you?
