I'm Not Sure What The Point Is With This

It may be a good idea or bad idea, but I don't think anyone who's publicly called it 'extreme' has ever given good explanation on why its extreme, they just try to say its extreme by implication. There's a lot of suggestion that people who oppose it want to 'repeal the Fourteenth Amendment' which is obviously ridiculous.

I've read the legal arguments about the Fourteenth Amendment, and the case against the birthright interpretation is that it all depends on what the meaning of 'the jurisdiction of the United States' had tot he people who wrote it. The claim is that it had a similar meaning to 'not subject to any Foreign Power', which is the way in which it was written in a previous civil rights act. They argue the only reason that particular language wasn't put into the amendment, and it speaks about 'jurisdiction', is because they wanted to ensure that Native Americans had citizenship. With that narrow interpretation in mind, they say, the Fourteenth Amendment can be read to exclude people who are visiting (as tourists) or are here illegally.

The credibility of this argument depends on how a court from that era would have understood the meaning of 'jurisdiction', which I haven't seen them try to establish. Even if the writers of the amendment had an intent, it has to be readable in the language of the law. In this case, it depends completely on what a court interpretation would have been at the time.
