I am in complete agreement with the views you have expressed about the state of affairs of Indian legal system and the practices and have upvoted your comments. However, when you say that the textbooks paint Hinduism as worst savages, I have to call out that hyperbole. That is a ridiculous exaggeration.
In fact I am in complete agreement with the following characterization, quoted from the wikipedai page you linked to.
Dan Golden of the Wall Street Journal described the
effort of the two Hindu foundations, as similar to those
by Jewish, Islamic and Christian foundations. Each group,
claims Dan Golden, vie for changes in texts for elementary
and secondary schools to cast their faiths in a better
light or in sensitive manner before children.
Those foundations are nothing but harbors of shills with a supremacist, political agenda and a wet dream of churchifying Hinduism under a central church.
I find a treasure trove of interesting things in the Hindu body of thought, yoga is not one of them, sorry. An over sold, over marketed artifact used to catch the gullible. To me striking things about its body of thought are its philosophical roots, the fact that they have been thinking deeply about such questions since antiquity, that not believing in any form of god is in complete harmony.
That said, for people coming from an Abrahamic religion, its a difficult thing to grasp. Hinduism is not 'a religion' if one goes by the notion of a religion in Abarahamic religions. It is worse than trying to map git commands to subversion. Its a very different beast, it is a meta religion (or more accurately a diverse collection of a very large body of thought and introspection, originating from a geographical region and built over time time, that visitors clubbed into a single pool because they werent sure what to make of it). It is more like a religion factory pattern for building your own religion that includes questions you should keep visiting in that process, and a more fundamental one, why at all (and when) should one even consider building one. It lays down thought processes, questions that one should consider and critique when one is forming ones own parameterized religion. People get confused whether they are talking about the polymorphic class or the object instance.
In context of its vast diversity and inclusiveness, Abrahamic religions would feel like that they are the same religion sans minor changes and all the fighting to be much ado about nothing.
