We were informed yesterday by our 5 year old granddaughter that mommy and this other woman were naked and kissing on the lips. This is the first we have ever heard or known about this. She has always had boyfriends and has never shown lesbian behavior. Not only that but this woman about 50 and my granddaughter is about 30, is homeless, bald head with a swastika on the back, big drug addict. Should we call CPS?
Your question needs some clarification but here's my answer. What is the reason that you think you need to call CPS?
You mention finding out that your daughter is gay from her daughter. Is the issue that she is gay?
You also imply that she is a neo-nazi, homeless and a drug addict. She was these things before and you didn't feel the need to intercede.
The only things that would raise a flag to me is if she was having sex (what I assume you imply by "naked and kissing") in front of her daughter. Gay or straight that's not appropriate. Of course she wouldn't be the first kid to walk in on 2 adults being intimate. Not something that requires CPS. Maybe something that needs some honest communication. Expressing concern that your daughter wasn't being discreet and that her daughter saw them being intimate wouldn't be out of line. If she didn't know that your grand-daughter witnessed them that's resolves that issue. If she did, and explained what she and her partner were doing, and told her daughter to knock on the door first, again problem solved. If she was having sex blatantly in front of her kid, then that's something else entirely.
But if your only objection is that she is gay, and somehow that means her child is in danger, then you are wrong. There are a number of other things that you imply with your question that might be risk factors, but suddenly finding out that she is gay does not make her a bad parent.
Who is homeless, your daughter or her girlfriend? Is your granddaughter homeless?
Do you have any reason to assume you granddaughter is in any danger other than your personal distaste of her choice of her mother's companion? Because if you don't have any reason to suspect abuse, all you'll be doing is saddling your daughter with a false accusation and cutting off any influence you have and likely never see your granddaughter again.
Firstly, from your post, there is no indication of abuse occurring, assuming the child seeing the naked kissing was on accident.
Secondly, your granddaughter is allowed to date anyone at any age or of any gender, race, or creed she wants. She's 30 which is 12 years past being a legal adult.
Lack of evidence of abuse won't fly for CPS. A lesbian relationship is also irrelevant in the context of child rearing. It's not contagious; it's not a disease. Don't treat it like one.
