I'm so worried and mad at my aunt for choosing to marry someone she's never met from a dangerous country
Why shouldn't she marry at first sight?
Because she's too blind to see what's going on, she is stupid
I do not think that she is stupid, but I do think that she should get to know the person before she gets married. How does she know that it is for sure going to work out.
She read a book by duke university that proved that it's always a good choice to marry at first sight
Since you feel so strongly about this, it might be a good idea to have a talk with her. Try to make her understand that sometimes these books are more opinion that fact, or even worse just wrong. Maybe you can get her to change her mind.
