I've wondered about this too because it seems pretty intense for one person to just change something that's in the Constitution. From what I've read, most legal experts say the president can't end birthright citizenship with just an executive order. The 14th Amendment is super clear about it—you'd actually need to pass a whole new amendment or a law through Congress, which is really hard. This is why federal courts have blocked Trump's order already. It's not just a simple power move; it messes with one of the oldest parts of how the US does things. Even the Supreme Court is hearing arguments about it, and from what I can tell, this is less about the president's actual power and more about what limits there are on using executive orders. Honestly, it would take so much for birthright citizenship to actually end, I'd be shocked if it could be done so fast or by just one person. It's a huge deal because messing with this could affect so many people and families. That's why everyone's freaking out over what could happen.
