As someone who is both pro-choice and a vegetarian I thought I should weigh in.
I was a vegetarian first...from the time I was a teenager. I was always very sensitive to anything that was suffering...because of the things I have been through and the person that I am. My views and feelings about the food industry used to be pretty extreme...but I have grown alot and now I do not take offense to people eating meat. I have no interest in controlling what people do with or put into their bodies...which is also a main reason why I am pro-choice.
That being said I don't think the issues are related at all. They are two very different and VERY COMPLEX issues and I think people SEVERELY oversimplify the connection between the two before giving it any real deep thought. It's VERY easy to not look at the big picture and say if your vegetarian you should be pro-life....but you have to look deeper than that. You have to explore the issues by themselves and the reasons WHY people feel the way they do.
There is NOT ONE reason why anyone is vegetarian or why anyone is pro-choice...people are INDIVIDUALS and have their own reasons for believing what they do or living how they do. Some people are vegetarian because of the health benefits, some people for cultural reasons, some people for environmental reasons, some people were raised that way...exc. There are also MANY variations to pro-choice belief's as well....the two systems of belief are NOT automatically incompatible.
I am Vegetarian because it is normal to me to be so. It is who I am. If I don't have to kill something to eat...why should I? I am pro-choice for many reasons. I am pro-choice because I believe that every woman should have full control over her person hood and bodily anatomy. I believe she should have the freedom of CHOICE...even if it is a choice that I personally wouldn't exercise.
