Actually, ideological dung is bad for science. For example, you are repeating the anti-scientific attitudes of the mid 20th century. The good news is that such anti-scientific prejudices are losing ground:

Recently, the negative conclusions of Holmes have been called into question. Paulhus et al. (1997) pointed out that "equally careful reviewers (Cooper, 1992; Erdelyi, 1985) have drawn much more favorable conclusions from the same literature" (p. 568). In fact, defense mechanisms and defensive processes are being discussed today across the broad field of psychology.
Although there were procedural errors in many of the early experimental studies of defense, the real sticking point in the refusal to accept the conclusions of these earlier studies was that they implied the existence of
unconscious cognition (see Lazarus, 1998). Yet, recently cognitive psychologists have rediscovered the existence of unconscious mental processes. Virtually every leading cognitive psychologist today accepts the premise that mental processes go on outside of awareness (e.g., Greenwald, 1992; Jacoby, 1991; Kihlstrom, 1987; Roediger, 1990; Schachter, 1987).
Currently, any basis for skepticism in academic psychology regarding the existence of "significant unconscious phenomena has crumbled in the face of recent research" (Greenwald, 1992, p. 773). Although this research has not focused on motivated unconscious processes such as defense mechanisms, it does provide support for the existence of unconscious mental processes, which is a requisite for defense mechanisms.
Psychologists in the field of social psychology have continued to (re)discover the existence of processes by which humans deceive themselves, enhance self-esteem, and foster unrealistic self-illusions. These defensive processes have been "relabeled or rediscovered under the aegis of social cognition or other current theoretical frameworks" (Baumeister, Dale, & Sommer, 1998, p. 1116). "Certain core concepts, for example, cognitive dissonance, were simply euphemisms for the study of defense mechanisms" (Paulhus et al., 1997, p. 563).
Freud didn't set back the progress of psychotherapy. It was the Freud wars that did it, the cultural war between those who were horrified by Freud and those who were enthusiastic. In fact, the decades following Freud, which are the years of the Austrian diaspora and creating of the psychoanalytical hegemony in the clinic were the years of Carl Rogers, Albert Ellis, Aaron Beck, and Fritz Perls, all psychoanalytically trained (except Rogers, who nevertheless was theoretically influenced by Otto Rank, an Austrian psychoanalyst of Freud's first batch of followers). And in psychology proper, they were also years of great discoveries which in large degree had nothing to do with Freud and were not set back by the Freudian hegemony.
There is no evidence of a "dark ages" in psychology in that period (which more or less covers between 1930-1970 or 1940-1980, take your pick), and instead it was quite fruitful both in psychoanalytic and non-psychoanalytically inspired developments.
So I call bullshit.
And if you have any intention of rebutting this, go ahead, make my day, I have a large stash of documented evidence to reply with, which I have been itching to unpack and throw around generously.

"Mind" as well as "instinct" are outdated words but still useful. Grosso modo, I do believe in mind (i.e. cognition and emotion) and instinct (i.e. inherited behavioral factors).
