I know these types I see and hear them every day, granola crunching, pro animal rights, vegans that are also adamant forest activists and in general what I like to refer to as a "CAVE" people (citizens against virtually everything). They do all of the above while they hypocritically wear leather shoes, jackets and god forbid pants, have piercings that are filled with metal rings that require various factory mining operations to extracate what is now in their face, live in wood houses, distribute paper leaflets with their various causes plastered in toxic ink (someone should really tell them paper is made out of wood) and drink gallons of starbucks coffee and soy products that require the destruction and conversion of tropical rain forest to plant.
You know the people who want highway like roads and walking trails with markers every fifteen feet cut in swaths through the parks and remote areas of Canada so they can access them with their carpet rat punt me dogs and styrofoam starbucks garbage and have the chance to enjoy nature without actually venturing very far from their honda shetruck because there are creepy things like "spiders and stuff".
These are the folks that know all about the wild, what is sustainable and what hunters should and shouldn't do because they read their latest activist rag miles inside the pavement prisons in which they live and have no idea where what they shove in their faces comes from.
Is that enough ammo for you? If it were me I wouldn't waste my breath. Just go for the short answer: nice leather shoes how do you think the animal that gave it's skin for them died? At least I am willing to do the animal the honor of doing my own dirty work.
