that the point/ key issue of the birthright deniers. (you) are subject to the jurisdiction of the country by sole virtue on being in it.  for them to stand will need to find a way to insert "born from a citizen" or redefine the whole "subject to its jurisdiction"  speaking from context, the 14th being "only for citizens" would go afoul of contextualist cause slaves were not citizens, the 14th was made then so their kids would be citizens by default.
