Who Will Protect Us From the "Protectors"

The folks at the ACLU circulated this around:

Proposing an amendment to the Constitution of the United States relating to marriage.
IN THE SENATE OF THE UNITED STATES
JUNE 25, 2008
Mr. WICKER (for himself, Mr. VITTER, Mr. CRAIG, Mr. ROBERTS, Mr. INHOFE, Mr. BROWNBACK, Mr. ALLARD, Mr. THUNE, and Mr. SHELBY) introduced the following joint resolution; which was read twice and referred to the Committee on the Judiciary
JOINT RESOLUTION
Proposing an amendment to the Constitution of the United States relating to marriage.
Resolved by the Senate and House of Representatives of the United States of America in Congress assembled (two-thirds of each House concurring therein), That the following article is proposed as an amendment to the Constitution of the United States, which shall be valid to all intents and purposes as part of the Constitution when ratified by the legislatures of three-fourths of the several States within seven years after the date of its submission by the Congress:
“ARTICLE —
“ Section 1. This article may be cited as the Marriage Protection Amendment.”
“ Section 2. Marriage in the United States shall consist only of the union of a man and a woman. Neither this Constitution, nor the constitution of any State, shall be construed to require that marriage or the legal incidents thereof be conferred upon any union other than the union of a man and a woman.”.

Yes, those are senators David Vitter, the serial-prostitute hirer, and Larry Craig, Mr. 'wide stance", who are going to protect marriage from all you gay folks.

Who is going to protect it from them?
