Pinhead is a nice way of calling someone a dumb shit or a dumb fuck, but the person using the word wants to whitewash their malice with an innocuous sounding word in order to give you a label with their analysis.
Never let anyone call you a pinhead, regardless of their education, status, or wealth because in letting them give you that label--it empowers their opinion and analysis and allows him or her to belittle you with condescending nonsense, including their desire to "help" you or to use you as a guinea pig to prove how much that he or she "loves" people.
