How is this a bias? It was only a matter of time. Islamic countries like Saudi Arabia and Kuwait(recently) have a ban on construction of church and any other places of worship. If you guys didn't have any issues with those rules, then you shouldn't have issue with the Angolan decision( if the news report is true that is).
As far as my knowledge goes, the majority of Christians in Saudi Arabia is of expatriates from other countries so they choose to go to Saudi Arabia on their own ( if i am wrong any Saudi can correct me) while in this case this is the indigenous population of the country. Secondly you are again assuming what we have issues with and what we don't have issues with so its most likely that you're assumptions aren't true. Anyways my real concern is that there shouldn't be a Myanmar style bloodbath so that there is nobody left to practice the religion in the first place.
