Its fairly simple.. Women have undergone diffeent levels of opression/discrimination virtually every where in the world for most of the last 20 centuries of recorded history. Its only recently that we as a race have woken up to this ridiculous situation and have started taking some corrective actions. This is easier said than done, since we are moving away from a mindset which has been prevelant for centuries and most of the old customs/traditions/laws actually contribute to this discrimination. So its obvious that the steps that get taken to correct this at times tend to over compensate since once you realize the problem, you always try to err on the side of caution. Thats why in most western countries, where the progress on this front is light years ahead of what we see in the subcontinent, laws are extremely protective of the women's rights
Hence the comment from S2 about an extremely high probability of landing in jail on hitting a woman (and rightfully so)
