I don't mind a salad, but we are omnivores and I have no issue eating meat (or byproducts like milk and cheese). I rather enjoy being at the top of the food chain.
There is nothing wrong with enforcing humane treatment and handling of animals. I think THAT is a very valid cause to fight for. Animals do deserve to live comfortably without the idiocy that they are somehow people too.
Eating meat = Suffering is every bit as stupid as Guns = Violence. It's all about doing stuff responsibly.
