The OP did not say he should have known anything, her question was whether she should accept it as a culture difference.

“In her culture, everyone would think as strongly as her”

You cannot assume what is believed in her culture, that is borderline discrimination.

Nor can you make such an assumption that an entire ethnicity would behave/react.

Especially if you are not from the specified EB yourself, or any other ethnic background.

I didn’t come here to argue based on one persons assumption about an ENTIRE ethnicity. Shocking.

Any validity you may have had in your argument before, has completely gone.

I didn’t come here to find world peace. But I have more chance of finding it compared to getting through to your clearly indoctrinated head and beliefs about cultures that aren’t you own.
