"Interpretation" isn't remotely the same thing as "policy," though you'll get no argument from me that many rulings by the SCOTUS seem to be driven far more by ideology than by the rigorous application of legal principles.
Agreed. But one would hope those dreaming up policy and then making sure some kind of policy is actually followed would at least start with a current interpretation of the law as it stands (which may be very old and enacted for different reasons) and then decide, Does this fit current and future projected Reality any longer? and then, Does leaving it harm our current situation? If the answer is Yes and No, leave it. If the answer is No and No, leave it (it can just sit, no need to change something not hurting us). If the answer is Yes and Yes or No and Yes, then it needs to be addressed.
I'm fine for leaving the 14th in place unchanged, however leaving it as is, is hurting us because a real number of people are coming here dropping babies, intentionally, so they're US Citizens. This isn't in today's day and age how we need to be letting people become US Citizens. At minimum we need a modern re-interpretation of the 14th, with an obvious nod to those currently made US Citzens under it by not nullifying that.
There are many counterproductive American rights and policies that are considered by one side or the other (NEVER both) to be essentially set in stone by the Constitution. So, for example, the same people who seem to think that the 14th Amendment can simply be re-interpreted in a less-immigrant-friendly way by the SCOTUS are the same ones who tell us with an almost religious fervor that any "re-interpretation" of the 2nd Amendment would be the worst sort of judicial activism. Sounds kind of unprincipled to me.
We could re-interpret or reassess the 2nd, I'd be fine with that. The problem is if you take out suicides and poor area violence (which is happening one way or the other, 2nd or no 2nd), our gun violence plummets to levels that are noise floor. Since I'm not going to begrudge someone that wants to end their life, nor do I believe telling criminals that they need to follow the law will make them follow the law, I don't see some country damaging need to re-address the 2nd. But we could (and for the 2nd, it seems it's constantly under attack anyways, so one could say we're already constantly re-addressing it).
