In her work with same-sex families, she has seen "no deleterious effect" on their children. "And if they are different, they tend to be more worldly, more open-minded and more empathic," said Bergman.
Her older daughter was freshman year valedictorian and this year, president of her class and a competitive swimmer. Bergman's youngest plays leads in the school plays and is on the soccer team and swims.
"My point isn't how special my kids are, but how ordinary my family is," she said. "Our kids bicker and they don't want to clear the table and do homework. They want to see videos and chat with friends."
She said her children have "everything in common with every other family who has adolescent kids."
"One message I have to anyone who opposes gay families is: Have dinner with my family," said Bergman. "Come to sit in my living room when the dog barks at the cat and the kids bicker and hug and argue over the remote and do their homework. It is so ordinary, it's funny."
As for Wahls, he said he is disappointed that the Iowa House voted in favor of the ban on gay marriage, but he is convinced it will not pass the state Senate.
His sister -- a full biological sister because the family used the same sperm donor -- was proud of his speech, and so were his parents.
"Both my moms were very excited and anxious to see how this turns out," said Wahls.
And to other children of same-sex parents, he added, "You are not alone and there is nothing wrong with you."
