Yeah, I'm not really convinced.

Just sounds like you feel very strongly about this and want to say "everyone who disagrees with me is racist".

The majority of the world's population lives in countries that don't do birthright citizenship.

Jus Soli definitely gets abused. Cheap international flights didn't exist in 1866 when birthright citizenship became part of US law.

I could see merit in amending those laws, perhaps not abolishing it but maybe tightening it to only apply to children of legal residents or something like that. That's a system that many countries use, including progressive European states.
