Hi! Are you an American citizen? I see you teach at a German university. You mentioned Ben Shapiro several times. I stopped listening to him about a 6 months ago or so, so I don't know what he's been saying recently. In the past, he was always clear that he was against abortion except in the case where the mother's life was at risk - which you detailed here. You and he would be on the same page in those scenarios. Each state has their own constitution, which is inferior to the federal constitution. Some states have abortion as a constitutional right. Some states laws allow partial birth abortion. Other states do not allow abortion at all, only allow abortion before a heartbeat can be detected, during the first trimester, etc. The laws vary. To get a federal constitutional amendment, the people vote on the amendment. It is highly unlikely at this time that the people of all 50 states, who have such varying viewpoints, will agree to one amendment to the constitution. Also, Americans are allowed to freely travel across state lines.
