The "Governator" of California indicates he wants to be The Terminator of the concept "by the people". He sent a message to California and its Supreme Court that he doesn't believe the people of California have a right to amend their Constitution.
Homosexuals and same-sex marriage advocates justify their argument to the world by framing it in terms of "equal rights". In Connecticut civil unions give same-sex couples the same legal rights as married couples (without the status of being married). Yet activists there were not satisfied until their civil unions were called "marriage". Such action implies to me that more than the same legal rights is desired.
