it goes without saying, but...

here's an example from nature that good parents don't have to be bio or straight. Read the sweet story HERE:

A German zoo says a pair of gay male penguins are raising a chick from an egg abandoned by its parents...
... the male birds, named Z and Vielpunkt, are one of three same-sex pairs among the zoo's 20 Humboldt penguins that have attempted to mate...
...The zoo said in a statement on its Web site Thursday that "sex and coupling in our world don't always have something to do with reproduction."
