Very precisely insightful. You've not only hit upon the bottom line of the pro-abort movement, but this is also true of the gay rights movement: an identity based upon sex without consequence.
The entire sexual revolution and ensuing condom cartel had this as its very reason for being: Sovereignty re: sexual liaisons & absolute control over consequences.
The self-identity of too many modern folk can be summed up simply: I shall be my own god of my behavior. Since I cannot live with my behavior being stigmatized or labeled as taboo, I shall seek to control others' behavior patterns as well. And since all relationships involve character issues--and sexual behavior with another person falls under the character umbrella--I will redefine morality in my own image or in our larger image as a movement that identifies with sex minus consequences.
