Really?
Let's look at what Osama bin Laden himself says. I will quote from a 1998 interview of Osama bin Laden by Frontline. The original context is here: http://www.pbs.org/wgbh/pages/frontline/shows/binladen/who/interview.html
"We know at least one reason behind the symbolic participation of the Western forces and that is to support the Jewish and Zionist plans for expansion of what is called the Great Israel. Surely, their presence is not out of concern over their interests in the region. ... Their presence has no meaning save one and that is to offer support to the Jews in Palestine who are in need of their Christian brothers to achieve full control over the Arab Peninsula which they intend to make an important part of the so called Greater Israel. ..."
"For over half a century, Muslims in Palestine have been slaughtered and assaulted and robbed of their honor and of their property. Their houses have been blasted, their crops destroyed. "
"They should all unite in the fight against polytheism and they should pool all their resources and their energy to fight the Americans and the Zionists and those with them. "
"The enmity between us and the Jews goes far back in time and is deep rooted. There is no question that war between the two of us is inevitable."
"The leaders in America and in other countries as well have fallen victim to Jewish Zionist blackmail."
"Once again, I have to stress the necessity of focusing on the Americans and the Jews for they represent the spearhead with which the members of our religion have been slaughtered. Any effort directed against America and the Jews yields positive and direct results - Allah willing."
"The fatwah is general (comprehensive) and it includes all those who participate in, or help the Jewish occupiers in killing Muslims. "
" He acted with zeal to make the Americans understand that their government was attacking Muslims in order to safeguard the American-Jewish interests. ... "
"We are certain that we shall - with the grace of Allah - prevail over the Americans and over the Jews, as the Messenger of Allah promised us in an authentic prophetic tradition when He said the Hour of Resurrection shall not come before Muslims fight Jews and before Jews hide behind trees and behind rocks. "
"We are certain - with the grace of Allah - that we shall prevail over the Jews and over those fighting with them."
"We anticipate this to happen to him and to the influential people who stand by him and who have sided with the Jews and the Christians giving them free reign over the land of the two Holy Mosques."
"And, while America blocks the entry of weapons into Islamic countries, it provides the Israelis with a continuous supply of arms allowing them thus to kill and massacre more Muslims. "
"I say to them that they have put themselves at the mercy of a disloyal government, and this is most evident in Clinton's administration ... . We believe that this administration represents Israel inside America. Take the sensitive ministries such as the Ministry of Exterior and the Ministry of Defense and the CIA, you will find that the Jews have the upper hand in them. They make use of America to further their plans for the world, especially the Islamic world. American presence in the Gulf provides support to the Jews and protects their rear. And while millions of Americans are homeless and destitute and live in abject poverty, their government is busy occupying our land and building new settlements and helping Israel build new settlements in the point of departure for our Prophet's midnight journey to the seven heavens. America throws her own sons in the land of the two Holy Mosques for the sake of protecting Jewish interests. ... "
"We say to the Americans as people and to American mothers, if they cherish their lives and if they cherish their sons, they must elect an American patriotic government that caters to their interests not the interests of the Jews. "
Thus, here we have Osama bin Laden himself giving the reasons for his actions. In the interview bin Laden does not complain about "modernity", "democracy", "secularism" and Western civilization. He only complains about Israel and American support for Israel. It is clear that the reason Osama targets American is because of the support the US has given to Israel.
Then obviously we should listen to Bin Laden right? You would beholden yourself to a satanic voice would you?
