5:51 Sahih International: O you who have believed, do not take the Jews and the Christians as allies. They are [in fact] allies of one another. And whoever is an ally to them among you – then indeed, he is [one] of them. Indeed, Allah guides not the wrongdoing people.
It is clear from the text that the Quran profiles Jews and Christian and orders the believers to avoid allying with them.
Is this not a sign of inciting disunity among humanity? It would have been better instead to mention the qualities in the Christians and the Jews that the Quran disagrees with, without using the term Jews or Christian to avoid unnecessary harm against those who are innocents(those who aren't hostile/who do not adhere to the vaguely defined concept of Jews/Christian by the Quran).
