Republicans are trying to use that "state's rights" thing right now. They don't think the federal government should have a say in abortion -- so they give it to state governments! What makes the state any more wise on the matter -- why not county or municipal governments?
The thing about Roe v Wade is really quite simple -- no government had anything to say about it. Under Roe, every woman (the concerned party) in every part of the country could make her own choice for herself. THAT IS WHAT LIBERTY IS.
@Twilight Hue, on the other hand, thinks "liberty" is whatever yields up the result that
@Twilight Hue thinks is the right one. It's a bit skewed, but the best he can do.
