Etymology: Detractors draws its meaning from a physical image: Latin "detrahere" combined "de-", meaning "down" or "away", with "trahere", "to draw" or "pull". To detract was literally to pull something down or away, and its early senses were concrete. The Latin noun "detractor" came to describe someone who pulls another person down by speech, which is where the sense of disparagement comes from. The spelling "depractors" in your request looks like a slip for "detractors", but if you meant a different form, let me know. The same Latin root gives "detract" and "detraction", both built on the idea of drawing something away from a person's worth or reputation.
