I understand some people know what happens in animal factories, particularly meat eaters, yet out of their own fear of acknowledging the cruelty and the power they have to help stop it, they prefer to ignore it and pretend it doesn't happen, carry on eating meat and supporting the industries while claiming they love animals.
I've been a vegetarian for 4 months and, after having seen Earthlings and learning more on how cows are treated and hens as far as obtaining their milk and eggs, I now want to be a vegan. As it turns out, it isn't so hard. I already love soy milk and have tried the dairy-free cheese alternatives. My most hard struggle is watching my parents in the grocery store buying pork and meats after trying to be a vegan and feeling saddened that they are, particularly around this Christmas time when turkeys, etc, are so in demand. Unfortunately you can't educate some people (like my parents, for example, though I've given up trying to explain to them what happens in factories and have decided to just get on with doing my own thing). It's just sad.
