Hmm, no, I can't quite find the underlying logic there... unless it is just that you're more consciously aware of the anti-fur lobbying effort. Also, it is now uncommon to see anyone wearing fur, which is both for practical reasons and the above lobbying - I seem to remember women in fur coats having cans of paint dumped on them! Neither wearing leather nor eating meat have so far elicited such responses in public as far as I've heard.

The reason that fur was picked on over and above other types of animal products was due to their status as "luxury" items, i.e. worn by the well-off. Animals dying "senselessly" for reasons that can be presented as non-essential/frivolous is an easy argument to make...
