Philip Tang might have embellished it a bit to get the point across. I guess his anger comes from the fact that Muslims are in denial about Muhammed, and that they continue to paint this rosy (false) picture of Islam whilst people keep dying in it's wake. As a non-muslim, I am actually sick to death of Islam and it's twisted doctrines.
If smashing Idols, murdering Jewish POW's and assassinating critics is not considered radical by you Muhuammed lover's, then it is easy to understand why Muslim leaders do not speak out about such radical behaviour.

More and more people are coming to see Islam for what it is. A violent political system garbed in a thin veil of religious mumbo jumbo.

Why continue to bring suffering to yourself and others by believing it to be true and from a God? Are you that locked in to being a Muslim that you lie to yourself and others? Are you able to admit you were wrong, change, and move on?

It would be simplistic if one were to say that the West represents what is good and the non-West represents what is bad.

The chief motivating factor for the Western colonial expansion was greed. Take the example from Japan, in the 19th century the Japanese leaders policy of isolation was challenged by Russia, England, and the U.S., making Japanese feudal leaders aware of Japan's vulnerability to superior Western firepower.

Japan was forced to sign a series of unequal treaties, which, as in China, gave Western nations special privileges in Japan. Britain used gun-boat diplomacy to sell opium and preached Christianity to the Chinese. All the expert kung fu fighters were no match for the British. Later the French joined the British (2nd Opium War) to plunder the Chinese capital and destroyed the Summer Palace.

The Japs were smarter than the Chinese in that they broke with their feudal past and began a search for knowledge that could transform Japan into a "rich country with a strong military." Education was reformed, and compulsory coeducational elementary schools were introduced . By 1912 the goals of the reforming movement called the Meiji Restoration had been largely accomplished: the unequal treaties with Western powers had been revised, the country was developing well economically, and its military power had won the respect of the West.

The policies and actions of Red China has to be seen in the light of how (in the past and presently?) the Chinese suffered under the hands of the Western countries and Japan when owing to pure greed they forcibly occupied parts of China leading to the signing unequal treaties. http://www.lexingtonbooks.com/Catalog/SingleBook.shtml?command=Search&db=%5EDB/CATALOG.db&eqSKUdata=0739112082

Mao did a lot of good for China in that he wiped away years and years of religious superstitions and traditions that got in the way of progress and rational thought. However, his cultural revolution caused much hardship for the Chinese people.

It remains to be seen if China would become a modern colonial power guilty of the sins that she accused the West of.
