I would not recommend a survey at all in this situation. You will get mostly predictable politically correct answers. A better approach is focus groups, or "sociological intervention" as Alain Touraine called. He used it quite effectively to study highly contentious political issues. Google it up or see: http://www.ualberta.ca/~cjscopy/articles/Hamel.html http://www.lancs.ac.uk/postgrad/jijh1/soc_links/french.htm http://en.wikipedia.org/wiki/Alain_Touraine http://www.sociologistswithoutborders.org/contributions/hsia_-_empowering_fo reign_brides.html
If you are serious about such a study - it may not cost as much as you think, and even less if you can get away with not paying the participants. Just make sure that your sample is highly purposive and includes representative of all factions of interest.
