I am not being vindictive. But trust me, a rising hindu nationalism is very dangerous for panthic identity , regardless of the sweet words they say. Heck I have been told on face some not so decent works about sikh gurus and sikh history , ridiculing its authenticity, and how they would have sikhs revert back to hinduism . This was after this guy saw Banda Bahadur animated movie.
The valve to control them is hindutva itself. They have a crazy wide network of organisations and the largest political party in the world at their disposal. The average muslim is poor in India , they have a hard time making ends meet, forget about crusading against infidels with an agenda. So why not support them ?
You're making two major mistakes: 1. You're being unnecessarily vindictive. 2. You seem to think there's an OFF valve to Islam that Sikhs can turn just at the right moment once it's served our purpose. You realise that's a fantasy, right?
