Does Allah say about the Christians?
You will surely find the most intense of the people in animosity toward the believers [to be] the Jews and those who associate others with Allāh; and you will find the nearest of them in affection to the believers those who say, "We are Christians."

Does Allah say about the Jews?
O believers! Take neither Jews nor Christians as guardian they are guardians of each other.1 Whoever does so will be counted as one of them. Surely Allah does not guide the wrongdoing people. 5:51 Holly Quran
لَّا يَنْهَىٰكُمُ ٱللَّهُ عَنِ ٱلَّذِينَ لَمْ يُقَـٰتِلُوكُمْ فِى ٱلدِّينِ وَلَمْ يُخْرِجُوكُم مِّن دِيَـٰرِكُمْ أَن تَبَرُّوهُمْ وَتُقْسِطُوٓا۟ إِلَيْهِمْ ۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُقْسِطِينَ ٨
Allah does not forbid you from dealing kindly and fairly with those who have neither fought nor driven you out of your homes. Surely Allah loves those who are fair. Holy Quran 60:8
"Allah does not forbid you from dealing kindly and fairly with those who have neither fought nor driven you out of your homes. Surely Allah loves those who are fair."
Means that Muslims are encouraged to treat people of other faiths, including non-Muslims like Christians and Jews, with kindness, fairness, and respect provided they have not harmed Muslims them for their beliefs.
FOR EXAMPLE: If some Jews hate Muslims then as a Muslim you can't really hate everyone who are Jews and judge about them since some Jews may treat Muslims fairly. And as a Muslim you can't really judge about people in general so you can't really do anything.
