I wrote what I recalled from memory about something I read about several years ago. I checked again and, according to Wikipedia, fornication is still illegal in 4 US states while adultery is still illegal in 17 states. The article mentions a woman being arrested for fornication in Mississippi in 2010 (article on "Fornication"), less than 2 decades ago. As far as other countries, I think I got fornication laws mixed up with adultery laws. Here's what Wikipedia says (article on "Adultery law"): "Among the last European countries to decriminalise adultery were Italy (1969), West Germany (1969), Malta (1973), Luxembourg (1974), France (1975), Spain (1978), Portugal (1982), Greece (1983), Belgium (1987), Switzerland (1989), and Austria (1997)" That's 3-6 decades ago so it looks like Europe regressed earlier than the US.
Wikipedia also says fornication is still illegal in Saudi Arabia, Pakistan, Afghanistan, Iran, Kuwait, Brunei, Maldives, Malaysia, Morocco, Oman, Mauritania, Qatar, Sudan, and Yemen, where any form of sexual activity outside marriage is illegal. It also mentions adultery still being illegal in many African countries. That's a sizeable chunk of the world.
You are very probably making a serious analytical error: a combination of "fact-blindness" and "cherry-picking".
That would explain why none of your fact-dependent claims check out.
You should deal with it.
Your analysis isn't bad overall, but an analysis that contradicts the facts is "negative information".
On point:
I knew about the old laws in US states, but removed them from my post.
I did learn while checking that they're sometimes used in plea bargaining, because they prosecution gets a conviction, but there are no penalties and nobody cares about extra/marital sex. /lol.
They're coming off the books slowly but steadily, but nobody really cares because they're not enforced.
For the rest, you shifted the goalposts. Adultery isn't pre-marital sex
I understand the trick of course ("pre-marital sex" is part of "fornication"; adultery is also part of fornication; therefore premarital sex is adultery - that's so common it has a name but I've forgotten it).
AFAIK among the bolded countries only Malta has English as an official language. It's very common in the others as a second language.
In every case they're old laws, and no more meaningful than the remaining US states.
Adultery is taken much more seriously in general, especially in formerly religious countries, because:
1. It is a civil contract - e.g. as used by the Habsburgs to take control of half of Europe
2. It used to be considered a commitment to a "higher power".
The last part of your post is:
(1) Muslim countries - no surprises there, but they lack the population and the country numbers to make your original claim true. OTOH I don't have a problem assuming without factual data that they have laws against pre-marital sex
(2) "Many African Countries". Big population, but a
lot of variation. If you exclude Muslim countries (mostly in North Africa) there are a lot of Christians in Africa, and a lot of ex-colonies with legal systems based on European laws.
You can't make a general claim about those
Doing so is as bad as what you did in the post I originally responded to.
If you can't provide solid data, you can't make that claim.
So: If you got this far without slipping into content-blindness ...
... I think I know why you're so careless with facts, and if I'm right, you can fix it easily.
All you need to do is start checking the article introductions in Wikipedia. Not because it's 100% reliable (though it's better than an AI /lol), but because it's
fast.
And maybe watch out for "cherry picking" and vague recollections from some echo-chamber.
