I don't have a problem with fur per se, but I do with the way it is farmed. Cotton is horrendous for the environment and kills more animals (and humans) but I don't see anyone weeping about that.
Smoking, couldn't really give a shite either way. I do think it's an irresponsible thing to do excessively if you have kids though.
Hunting I just don't get. I mean, hunting stuff like deer, yeah, I guess I do. At least the animal has had an ok life. Hunting foxes, no, it is totally pointless. I think it's pretty hypocritical to be a meat eater and be against hunting animals for food.
4x4s are just silly. People driving them in the city look silly, but if it makes them happy, whatever. In the country, sure, whatever. I mean the actual country, like in Scotland and Wales, not the Cotswolds.
None of those things really impact on my life, but one thing that does a bit is cocaine. A lot of people I know do it and it is very odd because it is completely indefensible really. I used to work with Colombians and they were utterly disgusted by the number of people in London on coke. For them, it was just a massive taboo and they would never take it. I don't take it either, but I know a lot of otherwise right on people who don't think twice about it, but turn their noses (arf) up at non fair trade coffee.
