It makes me wonder, can the reverse motive be made to work the same way? Or does strength of feeling such as hatred play an important role?

ie can we continually, in a high profile way, promote acceptance, inclusion, tolerance etc through use of charismatic leadership, education and so on (not necessarily coercion but possibly through regulation...)

Would that work? Or is it the focus and emotional investment of having something fairly specific to work towards that is the key to success eg getting rid of Jews, or getting that woman out of our laddish workplace...
