I wonder how something understood as truly subjective could, excepting gross distortion of the word, be construed as morality in any meaningful way. When pogroms and genocide are on the same moral footing as disaster relief and food banks, there should be some reconsideration of a position. When morality has been debased to mere preference and can be likened to color choice and musical inclination, what have you got?
To answer the question, obviously. A subjective morality has no philosophical basis for imposition and loses all ground for even judgement.
