I want someone to explain to me why the whole issue deserves a Constitutional Ammendment. Look at all the other Ammendments - they cover issues that have a direct affect on a major portion of the U.S. population. Why is this issue at the federal level? No other question of this nature is at the federal level, with exception of those pertaining to federal troops. Both age of consent for marriage and age of consent for sex are decided at the state level. Before we go adding to the document, let's take a look at what is already there - check the 10th ammendment. Any citizen that exercises a right granted by a state that allows any action, be it gay marriage or concealed carry of firearms, has that particular action recognized by every state in the union under Article IV, Section 1 of the Constitution. That's why you are able to drive in any state on you license.
