It's seems obvious that if you are raised to not eat meat then you will be very unlikely to introduce it into your diet later on, especially if it is socially frowned upon. People who have been vegetarians for a long time often are unable to stomach meat. Also, it's clear that some kinds of meat are already not eaten: do you think the reason people don't eat dog in the US is because it doesn't taste good?

So, while it's certainly likely that people alive today will always eat meat, generational turn-over could result in a world without meat eaters.

(I eat meat but do not eat mammals.)

> slavery and diet have absolutely nothing to do with each other.

No one is talking about diet. The part where you eat the animal isn't relevant morally. The part where the animal's freedom is restricted and is treated as an object purely for the pleasure of humans is.

What you're experiencing is cognitive dissonance. You're not a bad person for being raised in a culture that encourages you to not think about these things. You should try to look into where your food comes from even though our cultural biases that will make us try to avoid doing so or justify the atrocities when we do see them.

Please stop. We don't need another generic flamewar about this.
