@Kukailimoku, the Department of Homeland Security doesn't think the term "refugee" is "highly subjective."

"Under United States law, a refugee is someone who:

    Is located outside of the United States
    Is of special humanitarian concern to the United States
    Demonstrates that they were persecuted or fear persecution due to race, religion, nationality, political opinion, or membership in a particular social group
    Is not firmly resettled in another country
    Is admissible to the United States

A refugee does not include anyone who ordered, incited, assisted, or otherwise participated in the persecution of any person on account of race, religion, nationality, membership in a particular social group, or political opinion.

For the legal definition of refugee, see section 101(a)(42) of the Immigration and Nationality Act (INA)."
