I can read, you said "so many" which would indicate a large amount, perhaps even a majority.
And actually, with the exception of my food (i have no problem eating meat) you wont find very much in our house that is an animal byproduct. I have a bodhran which does have a skin made from animal hide, and an african drum. Outside of that, neither of us own anything leather, suede or fur (and that includes shoes), we also dont own anything made from angora - rabbit wool - (normal wool is not cruel). We dont purchase anything tested on animals, all toiletries, cleaning products etc are guaranteed not tested (or ingredients tested either). We dont even buy pet foods from companies that do animal testing (iams, proctor and gamble etc), as well as various other companies with very bad reputations, nestle etc. We dont buy from Body Shop as their owners are renowned for animal testing. The list goes on an on. a large percentage of our clothing is fair trade, and not just "fair trade" but bought directly from sellers in india and africa (the joys of the internet).
So before you generalise based on your experiences with some fashion veggies (and your relative who may or may not be a hippocrite) get your facts straight.
edit: i stand corrected. I have gone through the whole of down stairs and in addition to my bodhran there is a traditional roman game (similar to draughts) that is in a leather drawstring bag that the wife bought me at a roman day. Frankly im surprised she bought that for me, but there you go. Two items.
Honestly, to people concerned about animal welfare, your "most vegetarians are hippocrites" comment is like saying most black americans are murderers, or most english people are stupid, or most french people smell of garlic.
