For me it is summed up by the words:
Many of us including myself love theme parks but are put off by the unislamic environment
That my friend, is ISOLATIONISM. Because the culture is NOT Islamic, they do not wish to see it. Hence they are shielding themselves from a culture which is NOT their own.
If I said to you, I'd quite like to visit Saudi Arabia but I'm rather but off by the Islamic environment would you say that is wrong or right? Or rather, I don't want to go to Saudi Arabia because its an unchristian environment.
