Mom said "hamara yaha Shaadi me ladkiyo ko bech dete hai'

[Apologies. I know it's disgusting. And I had no other safe space to express it out. It took me years to even express this to anyone even on anonymous platform.]

My mom is being very sexist and favours my brother. In a discussion, she said I will get zero in dowry or inheritance. I said dowry makes sense but why inheritance. Anyway tldr she said - "hamara yaha Shaadi me ladkiyo ko bech dete hai" She said this at various occasions. It's very hurtful. ( Means - we sell our daughters and get money in wedding) ( It's not any norm in the our caste, neighborhood or any other place.. no one does this. Also I am financially independent and living far from years.)
