I am biased as a Hindu but I find that Hinduism stands apart here as a religion in that the emphasis is on one's own and the truths discovered therefrom rather than blindly accepting beliefs.
When I say I am allowed to be atheist or agnostic according to Vedas, your typical dumb Purohit also screams and tries to justify it's not that.
It's almost like Vedas or Upanishads or the values they emphasize have no place in preist centered medieval / modern "Hinduism".
Edit: And 'Dharma' in texts is used to refer to qualities such as 'dhriti' (courage) and r'ta (truthfulness), much more than its being used to refer to rituals. So I don't necessarily even need to read any of these to follow "dharma".
