Society has laws for two reasons. The first is to discourage behavior that is morally wrong, such as murder, kidnapping, embezzling, etc. The second is for the public good. Examples of this are speed limits, taxes, and sanitation laws. See the short video below for another good example.
About a week ago I was looking through headlines and saw something about how a certain politician answered a question about abortion. He had to apologize (don't they all?) because his answer didn't treat the question with much gravity as it deserved. A little further down the page in the article it gave a quote from another politician, who answered the question much more successfully. This politician's religious views state that abortion is flat out wrong, but he supports pro-choice legislation. I was interested to read his answer, which is as follows:
"I'm prepared as a matter of faith to accept that life begins at the moment of conception. But that is my judgment," [Politician] said on NBC's "Meet the Press." "For me to impose that judgment on everyone else who is equally and maybe even more devout than I am seems to me is inappropriate in a pluralistic society."
At first I was impressed with the answer and thought it was well thought out and tolerant of others' views. However, there was still something that bothered me. After thinking about it for a few minutes I realized what was putting me off. Aren't our religious beliefs supposed to be those that we hold more dear and sacred? Are we not supposed to stand up for what we believe to be true? Then I wondered what other beliefs this politician would put aside if religious beliefs were so easily cast off. That worries me.
We have a moral imperative to stand up for what we believe to be good and true, as well as to denounce what we believe to be wrong and immoral. If we simply allow things we believe are wrong to enter into our legislation, we allow our society to crumble. What would stop us from becoming like this?
And by the way, a pregnancy is not a choice, it is (except in the case of rape) a consequence of your actions. I know, I've been pregnant twice.
