As I get older, I find that I am trending away from animal products in clothing.
Not really a conscious thing, though I do find the wearing of animal fur distasteful, so much so that a while ago I gave away the few furs I had, although none of them had actually been purchased by me, and by the time I got them, there was certainly nothing I could do to save the animal.
Yet I can't help but agree with lilj that there is a certain hypocrisy in making impasssioned declarations on the subject of fur with a cheeseburger in one hand and a leather bag on one's arm, but then my own personal view is that there is also a certain hypocrisy in ceasing to eat meat and use leather on the grounds that they come from living things - so what are plants, chopped liver?
I guess I don't feel qualified to set myself up as some sort of authority or determiner of which life forms are or are not sentient beings, or beings more worthy of protection from aggression than other beings, etc.
My personal preference would be not to use eat anything that is or was "alive," but even though I have low blood pressure, a diet that consisted of only salt would really be pushing that envelope...
