I'm against the animal industry, but I am not a vegan.
However, I check where all my stuff comes from, I don't shop at supermarkets unless it is for (alcohol) drinks, get my veggies from a eco farmers market, get my meat from a farmer that I know (visit) treats his animals well & doesn't feed them all kinds of chemical shit, my eggs from my dad (has his own chickens, walking freely in the garden), you get the idea?
THAT will do much more to stop the animal industry then just fucking up your own diet by becoming full time vegan. I hope you check the source of your veggies too, as most Soy production is super damaging to the environment, rainforests anyone?
My ex her dad was hunting his own meat, never had so much free meat, free of crap (well.. you might find some left over bullets!), and being "wildlife", that shit is super expensive over here in the netherlands, while in finland it was cheaper then our chicken.
Humans are not meant to eat just veggies, that does not mean you can't stand against the industry and make conscious choices
PS. From my own experience (I did try vegan for about a year) - that shit is actually cheaper then all this processed food crap, so don't let money be the deciding factor. As for those people who complain about "I'd be hungry again 45 minutes later", I'd cook you a vegan meal that would fill you for the whole day, just.. try different stuff you know?
