Why do vegans object not just to free range eggs or organic milk?

If the prospect of witnessing or funding animal slaughter makes you uncomfortable, you should know that free-range hens and pasture-raised dairy cows are typically sent to slaughter before midlife. Just like their factory farmed counterparts, these animals are replaced by younger ones as their yields decline to unprofitable levels.

It’s also difficult and inconvenient to verify that a given producer indeed complies with claimed standards of animal welfare.
