Vegetarianism V. Veganism

I think veganism is more ethically consistent then vegetarianism in some circumstances, but not all. For example, if a vegetarian ignorantly consumes eggs and diary products without knowing the practices or who is harmed in the process of producing this good, then he or she is not ethically inconsistent because they have no access to knowledge they do not know. These cases may be extremely rare, but they can occur. Conversely, if a vegetarian consumes these products and knows the methods in producing these goods were harmful in someway then they are not ethically consistent.
