Well, then I retract my statement about your sole motivation being the appropriateness of sex, though I do believe it puts you in the minority of anti-abortionists. Congratulations on successfully raising your daughter.

And the Beethoven argument is an inconsequential "what if". If Beethoven had been aborted, maybe his mother would have been happier. Maybe she would have led a different life and eventually given birth to a legion of genius children destined to solve world hunger and broker a lasting peace treaty in the Middle East that everyone was happy with. Maybe she would have written symphonies ten times more beautiful than any music Beethoven could have given us.

And regardless of whether you think it is "adult" to accidentally conceive an unwanted child, the unwanted pregnancy is not an appropriate punishment.
