The way i think about it is
If someone doesn't eat meat because of the "meat is murder" bullshit, then they are discriminating against plants because plants have a completely different type of life. Either way you're killing.
So then i think "Hey, Hitler and Stalin both killed a lot of people, but Hitler is hated and had to suicide because he discriminated in his killings. Stalin lived a pretty long life and had a nice mustache."
So the next time you think of going vegetarian for the "meat is murder" cause, think this. Vegetables are alive and active. They contribute as much to the world as animals do (you know oxygen and pollen and stuff).
They meet all standards required to be counted as alive. They just dont have a cute face. You would be eating something over something else because they're different. You need to kill to live anyway, why discriminate?
