No I'm not wrong.
All of what you quote is true, but what you leave out is of course the highest risk, where a HIV- man or woman performs oral sex on a HIV+ man.
If you really think it's "very very low" risk of passing on HIV when an HIV+ man shoots his sperm and leaks his pre cum into the mouth of an HIV- person, then that's your choice to believe that. However, to spread the idea that that is "very very low risk" is akin to the pope spreading the lie that condoms increase the incidence of Aids.
HIV is passed on in, among other ways, semen to blood contact, which is why, for example, you are advised not to brush your teeth in advance of fellating a man whose HIV status you are unaware or unsure of. If you are really saying that you have no issue taking sperm and pre cum into your mouth from someone who is HIV+, then thats your choice, but to spread the untruth that thats "very very low risk" to others is not responsible.
I reiterate, the internet is not a place to take sexual health advice from strangers, no matter how well meaning they might be, and the only place we should take sexual health advice is from suitably medically qualified professionals.
