You can't dismiss all of academia outright and I have found it to be minimally compromised in the field of Religious Studies. My professors actually tended to be the voice of reason who'd point out propaganda that's being fed by the news media. I read the same things in academic texts as I hear from Hindu believers. And it makes sense, since there's an emphasis on respecting people of different cultures. If they misrepresented Hinduism, there'd be a backlash from people in India.

Anyway, feel free to point out something about which Academia is misrepresenting yoga or Hinduism in general.
