The case was about a challenge to the Texas statute and the right of a state to limit an abortion. The Court in Roe, ultimately created a Constitutional right to abortion, finding at that time that the state had little if any right to limit a fundamental right to abortion.
Congress, to my knowledge, never took any action. Of course, Constitutionally, Roe is about as suspect a case as one can imagine. It is undisputed that there is no Constitutional right, nor basis for or against abortion. Accordingly, the Constitution provides that the issue be left to the states. The opinion in Roe, had it been judicially sound, could have been written in one paragraph.
Congress, to my knowledge, never took any action.
I'm not going to spend a lot of time trying to recreate your point because this tangent isn't relevant to our discussion. I will say I agree with your first paragraph, I disagree with your second. Congress has passed a number of laws over time to address abortion practices. Were you present when they passed (multiple times) the partial birth abortion ban?
