I know exactly who you are. You are the lived experience of many vegans of the person that pretends to know more than us, as if every single person who went vegan didn't have a deep personal conflict with themselves before deciding to align their morality with their lifestyle. You know very little, yet try to advocate against us on our own perceived behalf, using your own sister like some sort of "I have a (insert group here) so I definitely know things". I don't need to understand you because I was you. The difference is that at some point, I was willing to acknowledge I didn't know enough about the moral vacancy of the situation and decided to learn more. The more I learned, the more I grew disgusted with our systemic murder of sentient life and how we didn't need this destructive mechanism to survive in any way, shape, or form.
