I'd say it's a big stretch to suggest that. Personality disorders are just that, disorders. So your theory about Cluster C being just "normal" doesn't acknowledge the fact that these types of behaviors are considered maladaptive, create functional problems, causing stress and disability. There are a variety of causes. Childhood abuse/neglect is a big one, but other factors such as genetics, environment, and life traumas both mental (such as losing a parent) and physical (head/brain injury) also play a role. It's not just related to childhood development, as adults have been known to develop disorders later in life. I suggest you read up on the different types of personality disorders to get a flavor for what's being discussed here. You can find links from the Wikipedia article.
