It's very simple. We think of dogs as cute and pigs/cows as ugly. That's all there is to it. You know how textbook illustrations make animals look grim and sterile? That's how most American children growing up before the internet saw cows because they were many miles away from the nearest farm. It's only recently with everyone having a video camera in their pocket are we able to see that cows IRL can be just as adorable.

Pigs do get uglier as they age tho so it's harder to PR. Any time I see pigs on Reddit outside of animal sanctuary subs, they are always babies.

That's not what happened. Gore won the popular vote but Bush won the electoral college. Most people agree its a dumb system in this day and age, but it's disingenuous to leave out that everything was done per procedure.
