I don't know, it doesn't make sense, it can't be a religious or cultural thing because in India, there are politicians of every creed.
Many years ago in the 60s I worked with Pakistanis, three, quite regularly, friends, I often went to their homes, all Khans, Jalal, Mohamed, and Saki, we worked on a machine that had 11 workers, of those 11, three were Muslim, one Hindu, one Irish Protestant, one Irish Catholic, and a Jew. We worked together, broke bread together and laughed and joked together. A few years ago, I met Jalal, he'd come back over here, there was a slap on my shoulder and a loud, drawn out, aaassalamu alaikum (sorry if the spelling is incorrect) It was his trade mark to emphasize the salutation. We walked around the town, sharing memories and went and had a cup of coffee, and he said, 'what went wrong, Micky, how did we let the madmen take power?'
So, perhaps, we are still letting the madmen have power.
