You may love rocky road ice cream, but others might hate it. You can't blame them - it's their opinion.
When creating an opinion survey you should take this into account. Especially if you are making an argument for one side of the issue.
If the survey doesn't completely cover all view points it will seem slanted. In this situation it would probably be best to use the Likert-Scale method. Since you can easily gage how strongly people feel about each side of the issue without peppering the answers with your own opinions.
