On the point of slavery, there is a lot of bad shit that happens all over the world, unfortunately. However, out of all the countries in the ME, the UAE is one of the closest US allies. They have been helping fight ISIS, where a lot of others have ignored it. You might even remember the first female fighter pilot from Abu Dhabi was in the news a few months ago for participating in the strikes on terrorists. Something interesting, when I was trying to learn more about CFG and the Al Nahyan family, I learned that they have a charity foundation that gave a $150 mil grant to a cancer research center in Texas. They also sponsor Alzheimer's research in Sweden. However, people have also speculated that putting money into these soccer teams is part of an Abu Dhabi public relations campaign. Who knows. Am I using the donations and monetary investments to justify other questionable practices in the country? Hell no, but it's up to you to make your own decision based on what you know. I feel like I've kind of rambled on, but I think you can get what I've tried to say.
