I never said I thought that.
Compare the number of people that have type 2 diabetes and the number of people that die every year as a result of it in the USA to the number of people that have HIV and have died as a result. Note that type 2 diabetes can effectively be prevented and controlled by diet and exercise but the numbers still dwarf the HIV numbers by at least an order of magnitude.
HIV is also almost entirely preventable, but I'm still seeing plenty of it.
