They were called sensitivity sessions. The humanist openly opposes the Christian moral implying it to deceptive and insidious. The Christian standards of propriety and decency had to go. The traditional sensitivities to right and wrong were standing in the way of such things as unity, meaningful dialogue and an amoral lifestyle. Bringing people together for the purpose of making physical contact was considered an effective way to destroy these traditional moral inhibitions.
Sensitivity training desensitizes the conscience of moral values.
This is an old psychological trick that politicians are very familiar with called Johnstonian psychology, that ignores any accusation and goes on with a very positive emphasis that often reverses the actual meaning. This was the effective way of breaking down our sensitivities toward each other. It was always carried out in mixed groups. The public school systems really went at it strong by holding the Sensitivity Training Seminars for their teachers. One first hand experience of a Christian Mother is typical of the method and outcome of this lunacy.
