there is no one hinduism, it's different all over India, at least ritualistically.
different flavors of it everywhere, it's not really a religion either, not in the abrahamic way, more a philosophy, and it's completely kosher to reject bits or all of it.
karma, the cycle of death and rebirth, the transient, illusory nature of the world, maya and attachment.. good concepts, one would do well to dwell on these matters sometimes.
no death penalties as mandated by the only true god or anything, and yes, you can have medium rare kobe steak, and wash it down with some merlot, no problem.
buddhism, I think is a much refined more modern derivative of it, also available in different flavors but the essence is the same
you can feel it when you travel to different countries, sri lanka, thailand, cambodia, whathavyou.. nicer calmer vibe from the people overall, very different to the west/middle east, which are also great, but just different.
people from the west and middle east will tell you as much about India, despite the poverty and the problems, generally happy people in these countries.
I tell them it's because there's not many who take religion seriously.
