Ffs, learn a little about veganism. I'm really tired of the "Nothing's perfect so I don't have to evaluate my behavior" argument over and over. Veganism is a way to reduce suffering, not eliminate it, and vegans already know that. The inputs and output that go into and come out of producing plants as food are less than producing animals and have far fewer determination effects on the environment. The balance is so far in veganism's favor that bringing it up is ridiculous. Any edge cases currently are an issue of either distribution or capitalism, so don't bother asking about herders in the middle of nowhere or people that only eat whale fat or whatever. It's irrelevant. Even if none of the edge cases converted, the impact of a general shift for the rest of the world would blow them out of the water. Please stop using this argument. It's not convincing or clever and people who have thought about the subject for any amount of time will think less of you for your willful ignorance.

How do you know somebody's a vegan? Don't worry, you'll be able to tell by the number of people desperately trying to justify eating animals to them.

I don't intend to read your response, so take the time you would have used writing it and use it to actually think about what you said or look up the nirvana fallacy.
