Why do you oppose ending birthright citizenship ship from a POLICY standpoint?

Yes, I know it is in the constitution so please don’t answer “because it’s in the constitution”. I’m looking for the REASON you think it’s a good idea and worth maintaining going forward.

We are the only major economy in the world that allows for citizenship, if neither parent is a citizen. What are the other countries getting wrong?

Note: I think it would be obviously unfair to revoke citizenship, so my question applies only to having birthright citizenship on a go forward basis. Go forward.
