I am of course, furious and exasperated on LW's behalf. I spent years trying to be friends with people who made me swallow a thousand 'micro'aggressions and I remain thankful beyond belief that my sweetie has my back. I would be shattered by such a betrayal, especially while pregnant.

Because that's what this is on the husband's part, a betrayal. He has to understand that part of his job, being from the majority and most powerful ethnicity and married to a woman of a different ethnicity, is to stand up to his family and rebuke them when they are racist to her. Which they most spectacularly were (atop the kajillion 'micro'aggressions of "please represent all of India for us thank you" and the bullshit about how someone born and raised in the US would be 'confused' by American food. Did I mention this one pissed me off?)

And if he's unwilling to understand that, or deliberately refuses to understand that, I think he's going to keep breaking her heart and helping his family grind her down.

I would hate to recommend that a pregnant woman leave her home and partner except under the most dire of circumstances, but I foresee two decades of the husband's family trying to "Americanize" the daughter and undermine the LW at every turn. If they told her to her face that her culture is "backwards" why wouldn't they tell the child that what her mother feeds her is 'disgusting', for instance?

I'm really worried about LW. I deeply hope her husband can love her enough and open his mind enough to catch a very necessary clue, but his reaction here doesn't bode well.
