Is there any law in the US mandating arranged marriages? If not, then it reinforces the freedom we have here, including the freedom to marry someone we have never met because our mother tells us to.
To those of us who grew up outside that culture it seems absurd, but to people from India living in the US who also want to maintain a connection to their culture, I won’t tell them they can’t do it. Having the government tell them who they can’t marry is just as misguided as telling them who they can marry. Your mother has a different, non-governmental influence over the decision, though.
