We can reliably screen for HIV (all blood donations are) why the fuck are homosexuals discriminated against over this.

except that the tests are (per cdc) up to 90 days late in detection. So you may get infected and spend 3 months testing negative.

And judging by OPs being german, where the rule (admittedly only since 2021) is "you may only have fucked one guy for the last 4 months", this seems like being on the safe side, but not completely excessive to me.

bigotry exists in all forms; but it's only the kind expressed by the uneducated & poor that gets rebuke and this one has been committed in plain sight since the 1980's by the wealthy and educated.

They do, but HIV infections can take a while to turn up positive while already being transmittable.

In addition to what @LwL said - It has to do with how testing is done, and that some diseases can't really be tested for. It is quite expensive, and is generally done on small samples from lots of people mixed together. If it is positive they split the batch and test again (look up binary search).

The lower the incidence rate of diseases, the larger batches can be done. Ditching certain denographics with significantly higher risks for certain diseases can make testing orders of magnitudes cheaper and faster. (Other groups, at least where I live, include people who recently changed partner, recently went abroad, have ever gotten a blood transfusion, have gone through a recent surgery, have recently been sick, etc. etc.)

tests have been available since the 1980's; they just don't want gays there.

Blatantly false. "MSM [men who have sex with men] accounted for 67% (21,400) of the 31,800 estimated new HIV infections in 2022 and 87% of estimated infections among all males."

When you consider that gay and bisexual men make up a small percentage of the overall population--under 5%--the fact that gay and bisexual men account for 87% of all HIV infections in men tells you just how alarming this is.

EDIT: For the people downvoting this - do you have statistics that you consider to be better, or more up-to-date? Do you want to refute them? Then post something and prove the CDC wrong. Downvoting because you don't like things that are factually correct isn't doing anything except making you look like a petulant child.

PS - wear a goddamn condom if you and your partner aren't 100% monogamous. Yeah, no one likes them, I get it. But that's a lot better than getting infected with HIV and needing to pay for expensive anti-retrovirals for the rest of your life.

i bet that the people who made this decision were dealing with the AIDS epidemic
