Stupid, you don't see the Jews Celebrating the Holocaust do you.
Islam is a "Religion of War", created by Islam's Greatest Holy Warrior of Islam, Mohammad.
As Mohammad's Muslim Armies were Conquering the Known World, during those times Mohammad needed the support of the Majority of Civilians to support his LARGE Muslim Armies, that were conquering "the Known World".
To require the support of the Civilians the "Religion" of Islam is born.
Rules are written down and became the Holy Koran, like it is Mandatory to join the Jihad against the Christians, Jews, Unbelievers (anybody that is not an Islamic Believer) no excuses accepted for not joining the Jihad, and Mandatory that All (including Christians, Jews, Unbelievers) support Islam's Holy Warriors of Islam (to defeat the Christians, Jews, Unbelievers).
All living at Muslim Nations must pay Mandatory Islamic Tithes (Taxes) to Fund the Holy Warriors of Islam.
Any attempts to convert to Christianity, Judaism other Religions is strictly forbidden (Death Penalty Fatawa), leaving the Muslim Religion is punishable including Death Penalty Fatawa (reason why "Once a Muslim, Always a Muslim", as cannot leave Islam, therefore Islam only grows, currently there are over 1.8 Billion Muslims Worldwide of a World Population of 7.5 Billion and Millions of Holy Warriors of Islam as Fully Funded and Supported by the over 1.8 Billion Muslims Worldwide).
109 Suras (Chapters) of the Holy Koran are the Written Declaration of War Against the Christians, Jews, Unbelievers.
The Holy Koran also states that the Prophets of the Christians, Jews, Unbelievers are False, and their Worship will not be tolerated.
Only 5 Suras of the 114 Suras of the Holy Koran mention "Peace", as "Peace" will be when everybody becomes Muslims (100% Subjugated to Islam and abandoned their False Prophets).
Islam is NOT a "Religion". Definition of Muslim from Muslims, an Islamic Believer completely Subjugated to Islam. For Muslims Islam is All as All Politics, All Laws, All History, All Culture, All Ways of Life and Death, All Religion, with these Muslim Laws, Muslim Politics, Muslim History, Muslim Culture, Muslim Ways of Life and Death, Islam superseding all nations laws, religions, cultures, politics, history, ways of life or death.
For Muslims the Holy Koran and the Ancient Customs of the Hadith are Modern Law.
This is why Islam can NEVER assimilate into the Cultures of other Nations. This is why France, Germany, Great Britain, and most European Nations are having problems as a "Clash of Cultures".
The 100% Subjugation to Islam of Muslims is done by Actions, not words. One of the most Common is Muslims to prove their Subjugation giving as much of their Property as Mandatory Islamic Tithes to Fund the Millions of Holy Warriors of Islam. Mandatory Islamic Tithes as Law stated by the Holy Koran are not only Financial, and do include (not limited to) Political Endorsements of Islam, Legalization of the Activities of the Holy Warriors of Islam, Material and Financial Support of the Holy Warriors of Islam including Sanctuary (especially at Mosques, a Holy Koran written requirement for Imams at Mosques to provide Holy Warriors of Islam Sanctuary).
Ramadan According to Muslim Madrasa (Madrasas, Muslim Schools) the Days of Ramadan represent the Defeats, Overthrows, Massacres of the Christians, Jews, Unbelievers, and the Sacrifices of the Holy Warriors of Islam.
The "Fasting" of Ramadan is from Sun Up to Sun Down, this represents the Holy Warriors of Islam eating drinking before Sun Up then going to War without food nor water, as the Sun went down the Holy Warriors of Islam left War and returned to their Encampments to eat and drink then go to sleep and repeated this until the War was over.
Example, the 25th Day of Ramadan celebrates the defeat of the Christian, Jewish, Unbelievers defenders of Mecca (original inhabitants). Mohammad then had Mecca (a building, a vault) built, to house the Religious Artifacts of the Christians, Jews, Unbelievers to prevent Idolatry (worship of Idols). This is common Muslim behavior like after the defeat of the defenders of Christians, Jews, Unbelievers at Jerusalem, Muslim Armies destroyed the Jewish Temple of the Mount, and built the Muslim Dome of the Rock on top of the destroyed Jewish Temple.
Your Actions to even have a valid argument or discussion.
READ THE DIRECT TRANSLATION (not the interpretation or opinions of idiots) OF THE HOLY KORAN. GO STUDY ARABIC (Official Language of Islam), THEN GO STUDY ISLAM AT A MADRASA (Indoctrination Classes to become a Muslim).
After your Years of Studies ask a Real Muslim (the minority opinions of the Million U.S. Muslims do not count, the Majority of over 7 Billion external to the U.S. facts do count) what each day of Ramadan means.
