Not much meat in that response.
Here's a starting point -- at the time of the adoption of the Constitution, none of the then-13 states had a law that prohibited abortion.
You sure about that? I'll pull and espola and say "source"? The Romans, for example, had laws regulating abortion. I'm pretty sure the Hebrews did too but I admit to not having a source.
You made the liberal case. The Constitution needed to evolve to address this issue, even though there isn't written into the Constitution an express right to privacy. The conservatives would rightly point out there is no right to privacy written into the Constitution and if the people wanted such a right the Constitution should be amended to address the issue. The liberals would reply that's too difficult given the stated methods. The conservatives would respond, fine, but you can't just give this right to rewrite the Constitution to a bunch of unelected judges. The liberals respond well how else do you get some modern principles into the Constitution. And the end result is you have a war for seats on the Supreme Court because they alone get to interpret/rewrite (depending on your point of view) the Constitution. Hence, Bork, Thomas, Estrada, Souter, Garland, Kavanaugh, Barrett.
p.s. I'd be very disappointed if I had the great misfortune to have you as my Con Law teacher. This is pretty basic law school 102 stuff on the dynamics of conservative/liberal arguements re Roe. You might need to go back for a remedial course.
p.p.s. @dad4 I totally understand now how you feel when I try and argue math with you.
