I think with a lot of people it is an "ignorance is bliss" kind of thinking.
There is also, with the Live Export issue, people saying, "Stopping Australian animals going to Indonesia is not going to stop other countries from sending their livestock."
You also get people who say, "What is one vegetarian going to do in the long run compared to the billions of people in the world."
So my attitude towards animal cruelty is that any measure in the right direction, whether it be a big or small step is still going to be positive.
I used to be the one who said what is one vegetarian going to do, now I'm awesome like the rest of us
