Two more big guns of the conservative movement confirmed today they are not participating in the Conservative Political Action Conference next month because of the continued participation of the homosexual activist organization GOProud.

The Heritage Foundation, the largest think tank in Washington and not known as part of the religious right, confirmed that it is not taking part in what has been the largest annual gathering of conservatives in the country. Heritage has been an active participant in CPAC every year for the last 10.

"We have withdrawn," said Mike Gonzalez, vice president of communications for the Heritage Foundation. "We have been there for many, many years at the highest level of participation.

"We believe in the traditional definition of the family," Gonzalez explained. "We believe in defending the family against any threats that come against it. We're not for gay marriage. We don't think institutions that have existed for millennia can be done away with at the drop of a hat."

Gonzalez emphasized that the "three pillars" of conservatism – economic liberty, national defense and social conservatism – are "indivisible."
