@JGoldman10,
We've told you why Greenland is probably one of the stupidest choices you could make for a setting for the fortieth issue of the comic you have yet to write the first issue of. No, it does NOT make sense to do "research" on every country in the world, or for that matter, ANY MORE countries in the world before you've gotten ONE country done in something you can shop around to people who might buy it.
Besides, if Greenland had street gangs, which it doesn't, they'd be made up of descendants of Eskimo sled dogs, who are so tough because of where they live and what their ancestors did, that they'd kick your "hero" street fighter cats and dogs' collective asses so bad it would end your comic right there.
