If you ask me the same question then my answer will also be Affirmative. I have also faced discrimination several times, sometimes gender based, sometimes ethnicity based and sometimes looks based. But one thing is for sure, that if I become filthy rich or at least an upper middle class, all or most of those discrimination will just wash away.I know you don't. Instead, ask them if they generally feel discriminated against in the country.
A street cleaner (irrespective of his/her religion) will obviously face discrimination but on the other hand even a so called Muslim who day/night gives kafir fatwas to every other person will also kiss his billionaire hindu boss's feet just to get a few thousand rupees promotion.
First thing, there was no nationwide systematic hate against Muslims before 2014. Second, Abdul Kalam was a Muslim just for the sake of name only. Third, he gave India nuclear power against a Muslim state, so at least India did not give a favor by making him president.Amazing but just like observational bias we also need to be wary of hasty generalization. For example, many Indians claim that there is no persecution of their Muslim minority because they've had a Muslim president
