I suspect here you are critiquing one of two things, either (1) The value of an ethic which permits wearing leather in spite of not eating meat or (2) How closely people live up an ethic of cruelty-free living, to which they claim to subscribe.. Re (1), I think that an ethical approach to reducing animal cruelty that prohibits eating meat, but allows wearing leather is incomplete, in so far as you continue to buy leather and contribute to the ongoing use of animals for that purpose. If your intent is to reduce animal suffering, then it is doing something, but arguably not aiming high enough. The same applies to vegetarians who eat dairy produce Re (2) If someone is not living up to their ethical standards, then it can be for a variety of worldly reason, such as lack of resourcefulness, lack of time, plain old laziness, whatever. Perhaps, also, they are taking a staged approach to a change that is challenging in an environment so saturated with animal products.If that is your concern, then you may as well ask why Christians sometimes lie or whatever, although it violates one of the ten commandments... human nature, I guess.
