Being parent-fluid does not mean that you lack parents. It indicates that you choose who your parents are.
Your selection is based on personal preference. You may elect to keep one of your own parents and discard another. Or you may choose to keep both birth parents. An alternate scenario is when you have lost one or more of your parents due to abandonment or death. This issue can be easily remedied by selecting one or more parents from the pool known as the human race.

Parent Fluidity means that you do not need to keep your parents forever. Once they have expired or irritated, you may spin the wheel and choose new ones. There is no limit to how many times you may amend your parentage.
You also can be loud and proud of having no parents. We support that lifestyle choice too.

The higher the chances of being discovered with one's pants down, pulling one's war face is obviously where the danger comes from. The more danger involved the harder (or softer) it is to complete the task in hand (snigger). The more dangerous the better. The chance of being arrested, pummeled by an angry father or having your hand severed by an arab's sabre means that you are a pro "Danger wanker."
