Needless suffering

I don't know anyone personally who would say that it's OK to cause needless suffering for their own pleasure. Yet everyone I know is doing it by eating animals and animal products.
If you are eating animals, you are either killing a sentient being or hiring a hit man to do it for you.
If you are using cosmetics that are not cruelty-free, you hired someone to keep a little bunny in a tiny cage and squirt a caustic substance in her eye.
If you ate an egg today, you hired someone at a hatchery to sort out fluffy, one-day-old boy chicks and throw them (alive) into a grinder.
If you drank a glass of milk, you hired someone to take a newborn calf from his distraught mother, tie him up alone in a little space for a couple of weeks, and then send him on a truck to the slaughterhouse.

For what reason? Habit, pleasure, laziness, willful ignorance. If you want to stop participating in a system that causes so much suffering, go vegan. It's easy and delicious, it's better for your body, it's better for the environment, but most importantly, it's better for the animals.
