Nobody is justifying homosexuality. On the basis you don't need to justify existing. Who would anyone justify themselves to?

Someone is trying to justify homophobia though. Luckily, we do not need to engage with one group more than any other. If other at risk groups used screening facilities in the numbers that gay men do, spread would be less. PHE, the public health body advising government and NHS for England are lobbying for more health education amongst female sex workers and hard to reach ethnic groups.

Historical data is of interest to gay interest organisations and those who despise them equally. Trajectory by meta analysis of all factors is getting better, and once we have better primary care data to go with HES (secondary care data) national trajectories will reflect a combination of all local predictions, weighted accordingly.

(That's for all health matters, not just sexual health. For a country where 95% of acute care is centralised by funding, we are shocking at giving a whole picture. We ended up abolishing The Health Protection Agency and incorporating its role into a larger public health body, perhaps (my opinion, not necessarily everyone's) the one good move in the reorganisation of The NHS. Crude incidence data will not be used in isolation from 2014/15. That said, historical data is excellent when auditing effectiveness of interventions. Ben Goldacre wrote a good article on it, and how some have abused it.)
