I provided a statement by the author of the 14th amendment that specifically denies illegal aliens are protectred by the 14th amendment. You can’t get more clear. Obviously your cited court decision is wrong.
You did not. You provided provided a statement by the author of the 14th amendment that specifies that illegal aliens are not protected by, in his words, "the Citizenship Clause" of the 14th amendment. Granted; illegal aliens are not "citizens."
But the Citizenship Clause is not the only clause in the 14th Amendment. The Due Process Clause of the 14th Amendment, by distinction, protects not "citizens" but "any person." Aren't illegal aliens "persons"? Or are they vegetables? Or animals?
