Birth of a child from criminal (illegal, undocumented) aliens should never enable that child to be assigned US citizenship. It is a reward for criminal activity and cannot be allowed.
There should be no reward allowed for any criminal activity in this country, especially criminal (illegal, undocumented) aliens deliberately sneaking into this country just so they can birth a child here and be rewarded by having US Citizenship given to them.
Also, the 14th Amendment was specifically targeted to slave and former slaves. It was specific to them in their time period and has no business being applied outside that context. Its application to criminal (illegal, undocumented) aliens is inconsistent with its context and intent.
