We atheists avoid logical fallacies. When it comes to selfish interests, we still behave illogically. I would like to present illogical arguments that (wrongly) justify cruelty to animals:
- Anthropocentrism: Humans have the sole right to life (sounds like the Bible, doesn't it?).
- Appeal to nature: Animals eat animals. It is a 'law' of nature. Just like men dominating over women was a 'law' of nature.
- Appeal to tradition: I will kill animals because everyone has been killing animals for centuries. Just like slavery was a tradition. Also domination over women was a 'tradition'.
- Appeal to emotion: We kill animals only because we don't want them to lead a bad life in the wild :( Wow! This is like saying we enslaved blacks because we could not see them suffer in Africa.
- Reductio ad absurdum: Why don't vegetarians also stop killing the bacteria in water?
- Appeal to horrorrrrr: Vegetarians are killing your children using deficient diets. LOL.
- False dichotomy: Either we kill animals, or we die. What side do you want?!
- 'All or none' argument: I cannot save all animals, so I will save none.
Perhaps the only logical argument in favor of eating meat might be about nutrition. However it has been proven that vegetarian diets can be at least as nourishing as non-vegetarian diets (if not more).
As scientific thinkers, let us at least avoid the above logical fallacies. Thanks.
