It's one thing to say that he's wrong (he is - terribly so). It's an entirely separate thing to say that he shouldn't be listened to because he's Hindu. Reject his arguments on their merits, not on his identity or ethnic/religious background.
Thanks for the advice.
No one would care what he has to say if he wasn’t a Hindu first generation immigrant.
That’s his whole shtick, what he’s selling. If he was Joe WASP, his noise wouldn’t make it out of the Yale grad school review index.
