Kukri thinks: if you get government money: you are a government employee.

As employer, the government can and should impose whatever conditions seem right. As employee, the individual should negotiate their best employment deal, then comply with the terms of that contract.

If the government has hired you to raise your children, you must raise them as the government/employer sees fit, or risk termination of employment. If you don't want the government to tell you how to raise your children, quit the job, or renegotiate a better deal.

Make abstinance or condom use a condition of employment. "Surprise" baby? Termination of employment. Underage pregnancy? Termination of employment. School drop-out? Termination of employment.
