But veganism seems so extreme. Why can’t I just become a vegetarian?

Unlike veganism, vegetarianism contributes directly to animal use. As previously established, using animals for our purposes is harmful to them and it is unnecessary. For example, milk and egg production are directly harmful to animals, as observed above, and we do not need to consume dairy or egg products. In order to avoid causing unnecessary harm to animals, we must avoid those products, as well as other products vegetarians tend to consume, like wool.

If veganism seems extreme, remember that this is only because we live in a society that considers it perfectly normal to annually exploit and slaughter billions of land animals and trillions of aquatic animals for such trivial purposes as pleasure and convenience. Surely that sort of violence is what is actually extreme.
