Not so much.
bastard - adjective usually offensive : born to parents who are not married to each other NOTE: This sense of bastard has not always been offensive. In fact, it was a relatively neutral term until as recently as the late 20th century, when it began to take on its offensive status. This shift coincided with a positive change in societal attitudes towards unmarried parents and a lessening of the social stigma of having children outside of marriage. The word bastard is still used relatively neutrally in historical references and historical fiction, but is usually considered offensive when used in present-day contexts to describe a child born to parents not married to each other.
