A taboo is broken:

"As Republicans we believe in limited government and we believe that the best way for the federal government to spur growth and jobs is to get out of the way and let small and medium businesses thrive,” said Congresswoman Ileana Ros-Lehtinen, who is speaking at the launch event and is a Republican co-sponsor of the Respect for Marriage Act. “We also believe in equality of opportunity rather than of outcome. Most importantly, we believe that the individual and the family are the central engines in our society.  The right for individuals to lead their lives without government intrusion is a bedrock conservative principle and it is much more than just about sexual orientation. It is about the fundamental rights we all share as Americans, it is about equality for all with no exceptions."
