Not eating eggs and milk, and not using fleece or wool is the epitome of stupidity.
Chickens (from personal experience) don't give a damn about their eggs most of the time. Every now and then a hen will get into a brooding mood and start to nest, and when that happens, she'll keep her eggs for the 21 days they need to hatch, but for the rest of the year, that same hen will pop them out and just leave them where she layed them, without a second thought. If the eggs are not taken by humans, they'll rot, or rats will get to them. Every now and then one will break and the chickens themselves will eat it. They love that stuff. Some hens actually love it so much that they'll break
their own eggs to get to that gooey inside... But, that's a bad habit that should not be promoted, therefore it's best to have the humans go gather the eggs every day so the chickens don't turn into baby eaters.
Cows, once they've had their first calf,
have to be milked. They were bread for that reason. If they don't get milked, they can develop a lot of health problems, their udders can get clogged, and they'll be in extreme pain. The baby only drinks milk for a few months, and the cow just keeps producing. That milk might as well be used by us. In exchange, we feed the cow and keep it safe from predators.
Wool and fleece, from llamas, goats, and alpacas, and sheep has to be sheered. If its not, it can grow endlessly, get caught in branches and rocks, and overheat the poor sheep. The sheep is not going to use it once it's gone, so why can't we?
These animals are in a symbiotic relationship with us. We help them, they help us. We keep them fed and healthy, they keep us fed and give us products we can use. It has been like this for thousands upon thousands of years. It's just beyond presumptuous and stupid to assume that you're more righteous than anyone else because you refuse to exploit animals. Animals don't give a damn if they're exploited. They just want to not starve, not be in pain, and not suffocate under their own wool.
