California bill would include child's gender in custody cases. Here's what opponents say.

Opponents of California Assembly Bill 957 made their voices heard outside the State Capitol. 

"It will elevate not affirming your child's gender identity, whatever gender identity they choose", said Erica Friday, a co-leader of the group OurDuty. 

Several groups and opponents to AB 957 and other bills making it through the California Legislature stood on the Capitol grounds to voice their opposition. AB 957, in particular, concerns adding language to judicial criteria that decide custodial rights in family court.

Essentially, parents affirming their child's chosen gender would be an extra piece of information used in making a decision about parental custody. Some other criteria involve the amount of contact a child has with a parent, the nature of the contact, and the health, welfare and safety of the child.
