Rick Santorum has a problem. The Republican presidential candidate has been dogged by gay rights activist Dan Savage since 2003, when as a senator he supported anti-gay laws, including against sodomy. Savage, an internationally syndicated sex advice columnist, took offense and called on his readers to wage an Internet war. He invited them to name, or re-name, a sex act after Santorum. Then he took a vote and created an anti-Santorum website with the new "definition." It's not delicate.
