McGrath, I didn't say anything about eliminating the risk. However, reducing the risk would reduce the number of infected people in the long term, which would in turn reduce the incidence of transmission further.

MtheGM, the education has to be good education. Education for sex and relationships can go right across the school curriculum. The approach must be holistic. It isn't about diagrams, anonymous questions about oral sex posted in shoe-boxes, the school nurse coming in to do a "special" or demonstrations of condoms being rolled on test-tubes. Context is everything. The context of sex and relationships is the context of our whole lives, no compartments. Education, at least in the UK, has never got anywhere near to addressing this properly. We get nuts and bolts spiced with religious moralising. It isn't only not good enough, it's the wrong approach.

As for "promoting this lifestyle," I'm not aware that that is what's done. In any case, good education would give people the confidence and nous to make good choices. It isn't a question of promoting one thing over another. It's a question of dropping the moralising and getting practical.
