Daniel thrived in Babylon eh?
Not suggesting you "should" stay... But it may be possible to be a light in a dark community/culture/region/nation.
I sometimes think the current U.S. Vice President is sort of a modern day Daniel...
For some of the reasons you mentioned above, we homeschooled our children, killed our TV for many years and did many other things to deal with the culture surrounding us.
It's a hard question you asked, but a good one. Watch for doors opening my friend.
A wise friend put it this way to me once during hard times.... "Ask yourself every morning: Who am I, and why am I here?" To glorify God and to enjoy him forever... You can do that at work, at home, in public, with friends, with coworkers, with enemies, or any other place you may be in this dirty old world.
Scott and Lawrence have given some good advice.
Remember, the good Lord places people where He wants and needs them, not necessarily where they want to be. It is His Will we are to be walking in and His Gospel we are to spread where ever we are.
Israel went through some difficult times right after the death of Christ. Famine, tribulation, and persecution scattered them because they had become comfortable in a Mega Church, if you will, and did not 'go into all the world'.
When God CALLS us to go to other places, He will make it clear. We often go when not called. He may allow it and even Bless us especially if we are truly doing our best to walk in His will and not our own. But, we need to do our best to listen for His still small voice and do His bidding.
Many times, as the demoniac, we are called to remain where we are and share what He has done for us instead of following our own heart even if that means being in the physical presence of the Lord.
Having said that, there are many times when God uses the pressures where we are to get our attention and move us to action. Pray, listen, act. He will guide you.
There are many countries with many opportunities. The majority of us here are very opinionated, prejudiced, biased, and proud to be where we are even though we acknowledge it is not perfect. Note that most of us did not PICK this place, God placed us here. Would we move? Not easily. But, if I had been born half way around the world and that was all I knew, would I move under the same conditions you speak of? Hard to say since I have not had to live through what you have.
Our prayers are with you.
He Is In Control, Have a Great Day, Brent
