When asked about the reasons for supporting same-sex marriage, the majority of respondents stated that "It is a personal choice to marry who you wish"(67.5%). This was followed with "Sexual preference is determined by nature"(13.6%), and "In order to work toward ending social discrimination of minorities"(12%).

The reasons against same-sex marriage were more varied, including "It could aggravate confusion about one's personal sexual identity"(21.9%), "It could cause social confusion"(21%), and "Sexual preference is a learned behavior"(14.7%). 12.5% of respondents replied "I dislike same-sex marriage for no particular reason."

The survey also asked how you would react if you learned that a family member, friend, or acquaintance was gay. 27.9% of respondents replied that they would treat the person as before; the most common response for women was "I would understand and support them"(36.4%) with men responding "I would seriously find out more and think about it."

Only 12.8% of men responded that they have met someone who has come out whereas 48.3% of women have. While causality cannot really be determined with this type of study, the correlation between knowing someone who has come out and supporting same-sex marriage is clear.
