"But, you know, there's still an argument, there's still ten states that outlaw premarital sex, and many more states where adultery is still outlawed and a crime"

This quote by Liam Neeson is describing the fact that, in spite of the progress made in terms of sexual liberty, there are still many states in the United States that have legislations restricting premarital sex and adultery. This is a suggestion that, while the country has come a lengthy way in regards to sexual flexibility, there is still a lengthy method to go. It is a suggestion that there are still many individuals who are not comfortable with the suggestion of premarital sex as well as adultery, and that these regulations are still in place in many states. This quote is a suggestion that, while progression has been made, there is still a lot of work to be carried out in terms of sex-related flexibility and acceptance.
