Vegans who think that eating animal products is wrong because "the animal didn't consent to being eaten/having their byproducts eaten!" Uh, generally speaking animals don't consent to being eaten regardless of species. Lions aren't asking antelopes permission to eat them either, and I don't see foxes asking politely before eating eggs. There's a lot to be said about the ethics of factory farming, but applying consent to the food chain is ridiculous. They're anthropomorphizing harder than Beatrix Potter.
And on that note, people who yell about how animal cruelty is bad while feeding their cats and dogs vegan diets. Cats and dogs are obligate carnivores, you fucking dipshits. If you want your pet to be vegan, get an herbivorous pet.
