Yes, dairy and eggs are cruel.
Cows are kept constantly pregnant, pumped up with hormones so they produce more milk, pumped up with antibiotics to counteract infections from constant milking. Their babies are taken away from them at birth. The male calves go to the veal crates (or the "lucky" ones might become beef cows), while the female calves will eventually join mom on the dairy line. There's also blood and pus in the milk--who wants that?
Eggs--hens are kept between 5 and 8 in a cage the size of a file drawer. Have you heard of battery cage eggs? They can't even move! When production declines, producers will "force molt" the birds by withdrawing food for a couple of weeks to "reset" the birds' biological clocks. Many hens die during this time. Baby male layer chicks, because they don't grow fast enough to become food and can't lay eggs, are killed at birth, often by being tossed in the trash to suffocate.
After production declines in both animals, they are sent to slaughter. However, a hen's body is so battered and bruised and has so little flesh, she typically is used for fertilizer, meal, low-quality potpies or nuggets, etc.

Eggs and dairy are actually crueler than meat.
