Because your stigmatising solution, forced screening and tracing, is criminalisation. No other way of putting it. Unless you force everybody who has sex, not just gays, to screen for HIV, chlamydia and herpes, you are criminalising one section of society. You cannot force medication or invasive clinical procedures, including screening swabs on anybody unless you either section them or a law is passed. As being gay isn't a mental illness in the civilised world, you need criminal law to back up enforced screening and tracing. To touch a person for clinical reasons without consent is assault, unless you make the person being assaulted the criminal. (I think I have that about right. I just about quote from The Health and Social Care Act 2008, preface to The Regulated Activities Regulations 2010. I am aware Scotland has a similar act, mirroring its predecessor, The Care Standards Act 2000, although that one didn't cover The NHS, just all other healthcare interventions.)

hence you are in favour of criminalising lifestyle, as you insist that enforced testing is the only option, when away from all of that, the health, substance misuse and social care professionals are seeing demonstrable success, set back only by idiots seeing a cluster and relating it nationally. Complacence is bad, but so is judging success by the size of the task ahead.

I don't hold you in contempt, after all I have no idea who you are. But I really do hold your views on gay people in contempt. Your pessimistic take on society in general is something I could debate, but knowing that somewhere, this irrational fear will pop out to play.

It isn't you versus me. I have yet to find someone who shares your "solution" for gay lifestyle. It is you versus respectability.
