What constitutes sexual assault?

The News Junkie at Maggie's Farm writes about the confusion surrounding the term "sexual assault."

If touching is assault then I have been assaulted by hundreds of women who have amiably touched my arm in conversation, and hundreds of men who have given me pats on the back. On a few occasions I have even had the experience of women tentatively touching me under the table and, for a guy, that is difficult to resist but it is not sexual assault.

Rape is violent, forceful assault with sexual intent. It is a felony. It is not equivalent to hand-holding, to a touch, or to a try for a good-night kiss on the porch. Equating normal social behavior with assault can only trivialize the reality of true assault.
