Genesis,
I used "clashes" in a metaphoric sense.
What I meant is that two opposite ideologies (Islamic Conservative Society vs. WC’s festivities) would “collide”, in the sense that they would be exposed to each other and a result of this sharing the same space, frictions (even invisible) would arise. Not necessarily physical clashes but discomforts in both sides.

To better illustrate what I meant, take the example of the silly rules for entering a bar/club in Doha. The rule itself is a result of the silent clash between the way the entire world sees night life entertainment and the way it’s perceived by Qatar. The silent clash occurred, causing discomfort in the Qatari side which led to a “corrective” measure that is now causing discomfort to the rest of the world who happens to be in Doha. Both sides hate each other and they only tolerate each other for the simple reason that both need each other.

As for the WC crowd, they generally lack the understanding of the Qatari society and they couldn’t care less about sacrificing their common sense joy of living for what they see as outdated and retrograde way of life.
