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.

So what ? Do you invite a Jehovahs witness' to a Chritmas celebration, do you invite a Muslim round to help you slaughter a pig ?

Many of us including myself love theme parks but are put off by the unislamic environment
So how would that be if it was...."many of us including myself love supermarkets , but are put off because they are not Kosher" ?
My god that's outrageous how dare they not fit in

But it's not about them hiring an atractionpark, it's about that they won't come unless there are no infidels.
Errrrr...it is about hiring a public venue , and has nothing to do with the presence of infidels , or are they hiring all new staff for the day ?

Conclusion, they don't want to fit in.
Conclusion , you have a problem with Muslims don't you
