With respect to what should or should not be discussed before a preliminary hearing, I'm not able to comment on the specifics of your son's criminal case without more information.
As for the lawyer calling you delusional, lawyers have certain ethical obligations in California. For example, a lawyer must deal honestly with others. Keep in mind, however, that the lawyer's main obligation is to their client (your son) and not you—even if you paid for the attorney and are allowed to discuss the case freely with the attorney.
