The human race
It is not a question of race, but rather, financial and medical resources. To point the finger and say, these people are more prone to, is not true. As a matter of fact, in the islands in the south, most std's were unheard of until the british colonized and spread the diseases. Same for the inuits and aboriginals. Most did not suffer, until the introduction of the so called white man, europeans who were infested and generated the diseases without protection. The first cases of std's recorded by man where in greece and in England, once called the pox, many were syphillis. So to pin point an exact race and blame them, you must first go to the origins or the illness. Syphillis was quite common in England as you look at old portraits, they mostly wore wigs and handkerchiefs, the reason their hair was falling out and their breath was horrible from them rotting alive. Popes, in the past who have been exhumed have been found to carry incredible amounts of std's..so there you have it, it may be more rampant in third world countries today due to lack of medicine, but originated elsewhere, usually stemming from beastiality
Many years of research do concur that many sexually transmitted diseases originated in the European regions of the world, common pratices such as home dwelling with goats, pratices, dogs and many other animals indicate that sexual practices did occur with these animal species. Syphllis can directly be traced to the sheep or goat and can only be passed with sexual intercourse from animal to human, then human to human after humans are infected with this disease. Although minorities do contribute today with higher counts of std's this Syphllis has taken a leap within the last 20yrs. One should look at the many government sponsored programs unhatched by the government to see clearly that this is more than just a mere coincidence. Programs like NSSM 200, Depopulation programs listed under Eugenics, Tuskegee experiments and a slew of other "programs" point clearly to the high number of std's in minority commuinities.
