You do have some good points, and indeed some of the traditions of your family are questionable, jahil. and Hindus are possibly the closest match to Makkan mushrikeen [the ideology that Islam battled against] that I know of
You seem balanced, MashAllah
The subjects you have touched upon are too much for me to reply to here, from my prospective. I will say The views you have expressed have Merit from your prospective. That much is true
Every point you have mentioned is deserving of discussion
What shall we do then, shall we discuss your families state first or shall we discuss whether Allah Subhanahu wa Ta’ala or shaitan [the rejected] is the provider of the ilm of the sufi?
This is what I had intended to discuss, as your background prospective was not known to me
Good points through out, with the detail given. The warning is that if you remove yourself from the Jamaah, by your beliefs, [no longer sunni but have wahabi beliefs on certain things] that would be a mistake. Stay with the community of Muslims that have existed since the time of The Prophet SallAllahu Alaihi wa Ahlihi wa Sallam, known as Ahlus Sunnah wal Jamaah [they believe in aid at Mazaarat for example, but the permission for young women to visit is not allowed according to my imams!!!] So everything has a prospective, Ahlus Sunnah wal Jamaah are not hindus or hindu influenced but everything has an Islamic prospective. It is true that sometimes what the people do is not inline with Islam, sometimes it is, and sometimes those who forbid an action do so too harshly or from a wrong prospective [not islamic, meaning shaitanic]
On your last point, of the attack of the shaitan, remember if he attacks you and you feel saddened that has been given in the Hadith as sign of Imaan
SubhanAllah
