it is a coordinated trend which was orchestrated by the usual LW handles. This happens every day on twitter, LW or RW, bollywood celebrities or businesses, Baba Ram rahim singh or other godmans, every vested interest generates a coordinated hashtag and trends it.
Also the RW twitter is not given the required exposure by media outlets in India (forget about the Western outlets) when they have their protests as well. This happens with many cases - e.g. Happened after killing of Kamlesh Tiwari. Many people celebrated the murder and were rightly condemned by the RW twitter group but Indian media did not highlight that.
