I did not say or mean to say it was exclusive to Muslims. It is a common problem in all religions that a lot of people do not act according to it's teachings.
As you are, I assume, familiar with Sura Fatihah, you may be aware that Muslims say that the words 'those who incurred displeasure/wrath' applies to the Jews, and the words 'those who went astray' applies to the Christians. Well, the reason we are told to pray not to become like them, is that a group of Muslims was destined to become like them. Infact, this is elsewhere prophecied. Indeed the verse does not say 'ghayril yahood wa nasaara' (not the jews and christians). Are the aggressive Muslims of today not like the aggressive Jews of the time of Jesus a.s. when murderous people like Barrabbas were deemed as heroes?
Here are some excerpts from one website discussing this phenomenon of the prophecied corruption of Muslims:
"According to the Qur'an, on the Last Day the Prophet (saas) will say that his own people will have abandoned the Qur'an: "My Lord, my people treat this Qur'an as something to be ignored
" (Surat al-Furqan: 30) It is also revealed in the hadiths that, during the End Times, the Qur'an's guidance will be disregarded and people will stray from it.
Near the establishment of the Hour there will be days during which (religious) knowledge will be taken away (vanish) and general ignorance will spread...(Bukhari)
There will come a time for my people when there will remain nothing of the Qur'an except its outward form and nothing of Islam except its name and they will call themselves by this name even though they are the people furthest from it.(Ibn Babuya, Thawab ul-A'mal)
A comparison is made in Surah Jumuah, verse 5:"The metaphor of those who were charged with the Torah but then have not upheld it, is that of a donkey carrying books
" There is no doubt that this verse applies as a warning to Muslims, reminding them that they must be careful not to fall into the same grave error. The Qur'an was sent down as a book of guidance for people to observe.
The Prophet (saas) said that, despite the fact that the Qur'an will be read, the knowledge and wisdom it contains will not be considered. This is another sign of the time of the End Times.
There will come a time upon the Ummat when people will recite the Qur'an, but it will not go further than their throats, (into their hearts).(Bukhari)
Allah's Messenger (saas) spoke of something and said: "It will happen when knowledge will be no more. " (Ziyad) said: "Allah's Messenger, how will knowledge vanish despite the fact that we will be reciting the Qur'an and teaching its recitation to our children and our children will teach its recitation to their children up to the Day of Resurrection?" Thereupon he (the Prophet (saas)) said: "Ziyad, do these Jews and Christians not recite the Torah and the Bible but not act according to what is contained in them?"(Ahmad, Ibn Majah, Tirmidhi)
"There will come a time upon the people when nothing will remain of Islam except its name only and nothing will remain of the Quran except its inscription. Their mosques will be splendidly furnished but destitute of guidance. Their divines will be the worst people under the heaven and strife will issue from and avert to them." (Mishkatul Masabih, Kitabul Ilm)
Is it not true to say that the religious leaders are a major cause of the problem? More details here:

It is a deplorable situation indeed.
Just as it is prophecied that Muslims will become like those who earned wrath and those who deviated of the Jews and Christians, it is also prophecied in Suratul Fatihah that there will be a group of the favoured ones. In the context of Jews and Christians, this is a reference to Jesus a.s., though it applies to all the prophets as favoured ones. And this is the prophecy of the coming of a Messiah among the Muslims in the latter days when corruption will have become widespread. It is the group of this Muslim Messiah that is referred to in the hadith:
"A time will come when my followers will become divided into seventy-three sects. All of them except one will deserve the fire."
Other ahadith state that the Jews were (at one time) divided into 71 sects, of which one was rightly guided, and the Christians were (at one time) divided into 72 sects of which one was rightly guided.

So, the Muslim world is divided into the three categories mentioned in Suratul Fatihah, and we are supposed to pray that we become one of the favoured ones, the followers of the Muslim Messiah and Imam Mahdi, the Guided Leader.
Peace.
