How unlikely would you say? This opinion alleges:
"14% to 18% of certain northern populations of Eurasian descent are immune to HIV/AIDS, Smallpox, West Nile Virus, and possibly Acute Leukemia, Cystic Fibrosis, Sickle Cell Anemia, Diabetes, and Hemophilia"

You're seriously trusting an "opinion" in a blog over your family doctor. I'm offended on her behalf.
I don't know much about that particular blog, but I don't trust it as it begins by lumping talking about immunity to HIV with talking about immunity to non-infectious diseases to which the discussion of immunity is not applicable. Specifically: acute leukemia (which is a catch all for a number of totally different blood cancers), cystic fibrosis, sickle cell anemia, hemophilia (these three are genetic inherited conditions), and Diabetes (there are multiple types again, the immune type I, the multifactorial type II and gestational, and the nephrogenic insipidus and central insipidus tha can be caused by drugs, toxins, trauma and other causes).
"Around 1% of Northern Europeans are virtually immune to HIV with Swedish people being most likely to remain uninfected. These highly HIV resistant individuals all possess a pair of mutated genes (1 per chromosome) that prevent the developement of the CCR5 cellular receptor that the HIV virus uses to infiltrate the cell. This genetric trait msut be inherited from both parents to have the most effect (homozygous). Inheriting the mutated gene from one parent provides some resistance but it is comparatively weaker (heterozygous). 10 -15% of Northern Europeans have this lesser immunity. By using molecular clocks, this genetic mutation dates back to the middle ages."
"Other ethnic groups possess lesser HIV resistance due to increased copies of the gene CCL3L1."

Using their numbers for %heterozygous it means that if you're northern European there's a 10% one of your parents has the allele, from this we get that there's a 1% that both your parents have it. That gives you a 0.25% of getting both alleles, ie being homozygous.
But pharmaceuticals are trying to target the CCR5 receptor, but the drugs haven't come into market because HIV virus can bypass the receptor and get into the cell through a co-receptor or change their afinnity to the receptor to overcome blocking it. Which means some homozygous will still get infected.
There is no commercially available testing in Canada, and OHIP will not reimburse you for getting it tested elsewhere. Not sure that you can't get it tested anywhere in the world, but it's unlikely that it's easy to find. Testing for this is mostly confined to research labs. And testing is only affordable when it can be produced in large scale, which it hasn't.
But to correct the people who say that being immune doesn't mean that you can't spread it that is incorrect. If you are truly immune it means you can't get it, and thus you can't spread it. This should not be confused with people who sometimes are carriers of a infectious disease but just don't get sick from it. They can spread it, just their body tolerates it.
But at the end one cannot hammer the point enough that one should not forget that HIV is not the only STI.
Herpes in incurable, and it's not just annoying blisters, in can spread to other organs and be fatal. It also can cause birth defects.
HPV is not curable, there are multiple subtypes and the ones that causes the warts are not the primary ones that causes cancers, so you can spread a cancer causing agent without knowing you have it. And it's not just cervical cancer, it's also anal cancer, penile cancer, throat cancer, and esophageal cancer.
More people are now dying of Hep C than HIV. There's no vaccine for Hep C and we don't have good cures. There are 4 subtypes and your chance of cure working is ranges from 15%-85% depending for many factors, but for most it's only about 50%. It's two medications a day in pill form and a weekly shot, side effects are close to chemotherapy, and treatment can go on for a year.
Gonerrhea and chlamydia may not cause symptoms at first, so you don't get cured, and may lead to infertility down the road. Can cause chronic prostate infection that is hard to cure because antibiotics don't penetrate the prostate well, women can get life threatening pelvic inflammatory disease.
Syphilis may go unrecognized at first, not treated, and then develop into a life threatening condition or one that leaves you permanently disabled.
And let's not forget that with our societies rampant use of antibiotics and antimicrobial left and right, were are getting resistant strains of everything. So your curable STI may end up being not so curable.
