Your own conclusions can come from your ass , it doesn ' t matter . Here is how I rationalize it . If humans never ate meat , I can ' t imagine there being enough space on the planet for all of us to live . I feel like human eating meat is the only way this world could work . Those are your own conclusions . It doesn ' t matter if they ' re a feeling or a guess that doesn ' t disqualify them from being your own conclusions on the matter . Especially since you say that ' s how your rationalize the reason to use leather . Your comments are just so offbase that it ' s overwhelming how much I would need to sit here and walk you through . You basically made conclusions about calculus , but you never learned anything about elementary math . But you want me to sit here and waste my time walking you through it , even though you don ' t even seem interested in it based on your knowledge of the problem and own admission to not looking things up . A simple google searchmeateatsresources earlier would have kept you from making your second conclusion . Go watch a few documentaries , such as Cowspiracy , if you ' re interested .
