After some wiki-research, I found that my facts on this were dead wrong.

It turns out that progressive Saudi Arabia was far more forward-thinking when it comes to the abolition of slavery than I had imagined, they abolished slavery in 1962 not 1965...

All smart assery aside, even today you are in big trouble as a Filipino or Eastern European maid or nanny if you choose or are tricked into setting up shop in Saudi Arabia

I was asking about equal rights for homosexuals, not slavery. As far as I know, very few countries qualify today.
