As a kid, when gay marriage was legalized in Massachusetts, one of the anti-advocates made the statement on the radio: "I am the gatekeeper for what is appropriate for my child, and the state telling my child that homosexuality is an appropriate lifestyle infringes on my role as a parent".

I asked my Dad what he thought of that statement, and he responded that gatekeeper was the completely wrong approach to parenting. The role is closer to a bodyguard or the secret service, you protect from harm and provide context when appropriate, but leave enough room to explore without your biases.

Self-sufficiency in ones own behaviors, responsibilities and statements should be your goal, just make sure they have a safe environment to explore and carve their own path.
