If you can't convince them, convince their children:

When "Yes on 8" signs began popping up on lawns in their Palo Alto neighborhood in 2008, Kathy and Lee Merkle-Raymond found themselves on the front line of the battle over gay marriage in California.

The same-sex couple, who were campaigning against Proposition 8, had to explain to their two young daughters why some of their friends' parents didn't want them to be allowed to marry. Then, with their daughters' encouragement, the couple decided to tie the knot before the ban on same-sex marriage took effect.

Their story is now the basis for "Operation Marriage," a new children's book that could make its way into classrooms and school libraries now that California passed a law ensuring that children learn about the contributions of gays and lesbians. -- San Mateo County Times
