In case you missed it, I have said repeatedly that I am not questioning whether or not the killing of the unborn is legal in the USA.
It obviously is.
I don't think that it always was legal in all states. This particular class of humans, the unborn, is unique from the others cited, slaves and women. The others started out in the USA with rights that were either severely limited or non-existent.
This one group of humans started out as a protected bunch and were then stripped of their protections by the Roe v Wade Decision.
This is the first time this notion ever crossed my mind. It's an interesting and unique little thingy. Have other very vulnerable groups been stripped of protections under our legal system?
Have there been other specifiable groups of humans stripped of protection(s) regardless of race, gender, creed, national origin or any other personally identifying features by our society in this country?
I suppose there might be a parallel in the genocide of the American Indian Tribes... Not sure that's a perfect parallel, though. There were treaties that were subsequently dropped.
Interesting concept.
Anyway, regardless of the morality or the ethics involved in this, the laws regarding the unborn have changed, the practice was and is ongoing and the act and the outcomes are generally the same across time.
As with the laws that were changed regarding women and with slaves, the laws regarding the unborn are only laws.
