It would seem Kegan is socially and politically liberal, but she is more of a classic liberal. Typically there are two roots behind being socially liberal. One is "the government has no right to legislate social morality, thus things like abortion, gay marriage, and prostitution should be legal." Others seem to have the root that "there is nothing wrong with gay marriage, abortion, and prostitution, the government should legalize and support them because my morals hold that they are not wrong." Basically, the first is from a root of less government intervention into social/moral issues. The latter would be more government intervention by supporting a moral code that one holds. I would say the first is more like classic liberalism.
That being said, I believe Kagan is a classical liberal when it comes to social issues as she clearly supports the personal rights of a woman who wants to prevent unwed couples from renting her property. This would suggest the stance that Kagan simply wants government to stay out of social issues, not that she is asserting her social/moral views on others. No one has to agree with my first paragraph about the roots of social liberalism (and I'm sure many would find them bogus), but I do believe that Kagan is socially liberal because she wants government to respect personal moral choices. I would have to side with Kagan on her opinion as well regarding this case.
