Possibly because the object of the exercise is to cherry pick historic statistics as a weapon to vilify sections of society.

On that subject. The change in law to allow home testing kits, once fully available, to be used to test for HIV is, in the opinion of The Terence Higgins Trust a huge milestone as many people still have issues coming forward due to the stigma that stems from bigotry. Concerns still exist regarding availability and supply and worryingly, people being in denial if they don't take up the support that GU clinic or routine hospital testing can offer.

Still around 25,000 people out there, in all classes, if meta analysis is accurate who may be carrying but not yet showing symptoms. Add the warnings around promiscuous lifestyle of young heterosexual people and older people who think STDs are a young person ailment, and we have a large issue building up.

One not helped by pointing at one possible source of spread and stigmatising them.
