So, here you're inferring that there are some ignorant Freepers. Now why would you do that?
Because it is regrettably true
The skylines in question are not the mud hovels and tents of wandering Bedouins but the indications of civilized society. One of the buildings happens to be the tallest building in the world and two others were the tallest buildings. All are visible proof of civilized society.
The dogma is that there is no Moslem civilization and that ignorant claim is belied by overwhelming number of facts.
