This is madness and I see Sweden as the new Sodom and Gomora. Why among everything on earth,it is sex that is forbidden by God without getting married that they want to take as sport. Very soon another country will come up with their own competition called smoking competition. I will never watch or gamble on such nonsense,it is demonic.
You are being more personal than logical in your statements, You are a Christian and not everyone is, Your culture rejects it, while Swedish culture might promote it, so what is entirely a wrong practice for you would not be for another person. I really think that the problem is not about being demonic, but the decline in morality that it would further propagate. Pornographic contents and games have done a whole lot already, introducing it in the casino would further the damages to a new level.
On the advantages, it would give a very big boost to the world of pornography and make it more popular, meaning much more dividends to the governments of the countries they operate in, would even give the Swedish government a very great revenue if they monopolize the sport.
Ponographic content have damaged the creativity of the youths to a great extent already, and more advances in that direction would further increase the drive of the younger ones into it and keep promising us a future of morons. I personally would not promote it on the grounds of morality and psychological impediments on the society
