The whole thing is a grey issue and shouldn't be used as rallying cry by the political parties, unfortunately you have the right saying that abortion is wrong and on the left you have the rise of lunatics like Kathy Tran who wanted to see abortion allowed up to the point of birth saying that the infant would be delivered, kept comfortable, resuscitated if that's what the mother and the family desired, and then a discussion would ensue between the physicians and the mother. It's probably the only thing I agree with Hillary Clinton over, that abortion should be safe, legal and most importantly rare.
From a legal standpoint the Supreme Court is correct, there is nothing in the constitution that grants an automatic right to abortion. There is also nothing stopping Congress from passing a law that gives that right. If anything NO right should be automatically granted by the court, it should always go through legislation so that there is public accountability.
The problem is that there are too many people who aren't going to bother reading what's actually been said and jump straight into rioting. There have already been cases of pregnancy centres and charities being firebombed not to mention the idiot who decided to go and assassinate a member of the supreme court.
I can see this getting bloody.
