The "Angered upon" and the "Led astray"

I recently came across this:

Nevertheless, the idea that Christian belief and observance is illegitimate is deeply rooted within Islam. The Islamic prophet Muhammad composed for the Muslims a brief prayer, known as the Fatiha (Opening), that became the cornerstone of Muslim prayer (it is recited seventeen times a day by the Muslim who performs the five daily prayers) and the first sura of the Qur’an:

In the name of Allah, the Beneficent, the Merciful.
Praise be to Allah, Lord of the Worlds,
The Beneficent, the Merciful.
Master of the Day of Judgment,
Thee (alone) we worship; Thee (alone) we ask for help.
Show us the straight path,
The path of those whom Thou hast favoured;
Not the (path) of those who earn Thine anger nor of those who go astray. (Qur’an 1:1-7)

Even this, which has a status among Muslims analogous to the centrality of the Lord’s Prayer for Christians, has a polemical edge. Traditionally Muslim divines have identified those who have earned Allah’s anger with Jews and those who have gone astray with Christians. The Qur’anic commentator Ibn Kathir (1301-1372) explains that “these two paths are the paths of the Christians and Jews, a fact that the believer should be aware of so that he avoids them. The path of the believers is the knowledge of truth and abiding by it. In comparison, Jews abandoned practicing the religion, while the Christians lost the true knowledge. This is why ‘anger’ descended upon the Jews, while being described as ‘led astray’ is more appropriate of the Christians” (Tafsir Ibn Kathir, vol. 1, 87).

I really can't tell if this is true or not, and if it is, do all the Muslims in the world know it I mean do they know that they are cursing Christians and Jews 5 times a day, every day of their lives?
Not only then but even in their funerals and wedding proposals and mostly any type of agreement?
So yes my son I would love to give you my daughter as your future wife and while we're at it let's curse the Christians and Jews!!!
