It IS the issue, because how can you pass an unenforceable law?
The whole abortion debate centers around when a fetus becomes a life. There are different opinions about it. Like I said, I don't know and I don't really care that much either. I don't personally like abortions so I don't encourage them or take part in them. But let's fix the monetary system, end all of our wars (drugs, terror, iraq, afghanistan, korea, poverty, obesity), return to federalism, end corporate and personal handouts and entitlements, stop big brother, get rid of the TSA, stop infringements on 2A, remove malum prohibitum laws from the books, make it more difficult for laws to get passed, reform the justice and corrections systems, get the insurance companies out of our medical system, substantially raise or eliminate most speed limits, lower the drinking age to 18, dismantle the department of education, and cure cancer and then we can talk about abortion. At the state level.
As for politicians making their moral beliefs law: I don't care if it's normal, it's not right. We a have a constitution partly for preventing emotions and passions from getting mixed into political action.
