I don't think anyone in their right mind would say that "consent and privacy" by themselves are the two criteria by which one establishes whether or not sexual behavior of any kind should be legal.
However, when it comes to homosexuality, unmarried sex or adultery between consenting adults in the privacy of their own homes...most Americans simply don't want police barging into people's bedrooms and arresting them.
Rick Santorum should clarify if is supporting the idea of police arresting and jailing adults for private acts of adultery or homosexuality.
I beg to disagree. The two ideas at work concerning this issue are the issues of consent and privacy. If you are aware of others, I'm willing to listen.
