"All things can be made lawful, but not all things are Spiritually constructive and beneficial.” 1 Corinthians 10:23 Think of Constructivist as being proven "truth in love" constructive criticism; beneficial albeit not always enjoyable to both give nor receive but the fruits are worth it all.
Constructivists are independent thinkers disciplined to altruistic highest ideals and USA founding Father's Judeo-Christian principles of objective truth.
