ya.. Mail order brides.. I don't necessarily agree, but it's their choice to participate, or atleast supposedly. I think the rationale is they come to the U.S., get citizenship, and live a much better quality of life than living in extreme poverty or in countries where they have virtually no rights. Most are very subservient by nature do to how they are raised over in Asia, Arab nations, not sure about Russia
Google "mail order brides", the first 2 results are Russian brides and Asian brides...
