There is no such thing as a victimless crime other than such things as personal illegal drug use. To think that insider trading is victimless is absolutely absurd. It isn't like doing drugs in the privacy and anonymity of your own house, it is affecting a system that affects everyone. Anyhow, enough of this derailment.
"affirm that the unborn child has a fundamental individual right to life which cannot be infringed" to me sounds like there are no exceptions. As per that wording, if you include exceptions within this proposed amendment, then the 'right to life' would indeed be infringed. Thus, the amendment would not have applicable exceptions when it comes to rape, incest, when the mother's life and health would be in great peril, if subjected by law (i.e. forced) to give birth.
This is what bugs the hell out of me about the Republicans and conservatives. They always talk the talk about how the government should not, under any circumstance, infringe on individual liberties. Yet they pull shit like this, such as restricting whatever women do with their womb. The more accurate description is "we are against governmental intervention with personal liberties... unless the liberties fail to pass our litmus test of ideology."
And about the Constitutional amendments. It is extremely dangerous in proposing amendments to the Constitution that fundamentally restricts freedoms of the populace. Amendments are supposed to remove restrictions on individual liberty, not impose them. Such as the 13th in ending slavery, 15th in allowing said slaves to vote, 19th with women's suffrage.
Amendments that restrict personal freedoms have been met with disastrous results. The classic example is the 18th amendment: prohibition. It was billed by the temperance movement as medicine to solve all of societies ills at that time. And it was so wrong. People drank anyway, and when they did, they drank in unsafe and unregulated speakeasys, they drank unsafe and unregulated alcohol, that was cut with the other toxic alcohols such as methanol and isopropyl. Not to mention the emergence and proliferation of the modern-day mob and organized crime. Thankfully lawmakers came to their senses and repealed it a few amendments later.
Although if such an abortion ban amendment is put in place, I don't think the problem will be as large in magnitude as prohibition, but the problem will still be significant. The doctors and personnel of abortion clinics will be out of jobs, adding to unemployment. Black market / back alley abortion clinics will rise, which will include unsafe unregulated drugs and crude methods not far from using a coat hanger. And there isn't any guarantee the resulting babies that the mother was forced to carry to term will live in a perfect "middle-class Christian family." Although there are exceptions, most will live in relative squalor, and the financial burden on the mother will be exacerbated, thus average quality of life will decrease.
