I think you're right, but it has never made sense to me to seperate the nationality of a child from that of their parents.  Or, for that matter why the location of your birth would decide your nationality.   

I believe the original intent was intended to protect slaves, (taken by force from their home) and their children from being force to be 'sent home'' to a nation they had resided in but would not know in the present.. Being as the parents had no 'choice' to be slaves, the amendment makes sense, for that time.

But yea, changing an amendment is very difficult.    If it was your choice, would you do anthing to the 14th?

Interesting that Repubicans were afraid Democrats were going to take away the new given rights to all black citizens after the war.    Funny how the character of parties change.    I never thought about it, but would black slaves qualify as illegal alliens or undocumented immigrants?
