After snooping around, i learned a few interesting things.

One: in japan, the amount of muslims is very low. Only around 100k.

Two: only 2 percent of the population in China is muslim. However, that's twenty million people.

Pretty sure that's more than the amount of muslims in America 

China is an authoritian government, 80+% of the people have no religion there period, which is how the state wants it. 

Religious extremism does seem to be a growing - or at least more public issue these days not helped by the migrant crisis and the tension it brings on both sides. As for people becoming more divided over all, I'm not so sure. I'd like to think that recent hostilities and raised blood pressure around the world are just part of the unfortunate backlash that comes with progress. People who have had it good historically are pissed off at how their environments are changing against them and they're lashing out. Deep rooted prejudices are boiling to the surface as their worlds get smaller. Such pissed off people are how Trump is seeing so much success lately. I hope that these times are just the first half of the "it has to get worse before it gets better" saying and these extremist groups adjust and start fading away soon. I really hope things don't have to get any crazier before that happens.

Unless you're willing to debate in a way where you're not gonna take personal digs at me when you don't have a point, go pester someone else.

I'm just concerned for America. I seriously don't want anything like the 2007 economic crisis. 

22/11/1963 a book by Stephen King had a good part basically it is about a man going back to the 50's and how life was great in the 50's. People were friendly and helped each other and lived like real community's but then the main character wants to go the toilet and reads a sign saying 'coloured people toilet this way' and it leads outside to a field that is filled with poison leaves that the average person probably doesn't know and that was accepted.

You don't have to go that far to see what a real seperated country really was.

Couldn't you have at least checked whether or not these countries have terrorist attacks?

No he's right, the problem is with the older generations who can't let the past be the past and bring things like racism over to the next generation. There are people who actually want progress you know.

As for divided society, any thoughts on whether people tend to move to places that match their world view? Then they just end up living in bubbles.

For example, I'd be interested in knowing how many conservatives happily move to California or NYC each year. Or how many lefties move to the southern states?

Another part of this is gerrymandering. If you make it so that your district is guaranteed to be Democrat, for example, then the people running don't need to appeal to the broader electorate, they only need to appeal to the Democrat base, resulting in more extreme candidates.
