Let me make this clear. I am against any wasteful killing of animals, and I am against treating any animals cruelly when they are alive. That said, if you wear leather, but condemn using snakeskin, I find it a bit hipocritical. People seem to think the species they love are somehow special, or deserving more protection than others.
As for why people like snakeskin products, it's obvious. Snakes are absolutely beautiful. I still remember the first time I saw a red-tail boa. The color and pattern was stunning. I'd rather have one as a pet than as footwear, but I definately see the attraction.
