The case in point being his language in a poll campaign in Shimla, where he described Sunanda Pushkar Tharoor as 'Rs. 50 crore girlfriend.' He was of course alluding to the shady IPL dealings which cost Tharoor to lose his post as MoS in the MEA. In that sordid affair, Tharoor claimed that he had nothing to do with Ms. Pushkar, but went on to marry her in a few months!
Well, getting back to the point, Modi's words have caused a political furore, mainly because of the sexist overtones. However, given that Mrs. Tharoor is not a politician, it was rather unnecessary to draw her into the debate, that too with such cheap language. Modi would do well to remember that perceptions matter in politics and although his place in Gujarat is secured, on a national level, he will have many more constituencies to address and a bit of political correctness would not do him harm.
