What is the meaning of "the claim of the pre-Islamic age of ignorance" in the hadith?

Question:
The claim of the pre-Islamic age of ignorance?

Answer:
It is fanaticism. This is the claim of the pre-Islamic age of ignorance: fanaticism for one’s fathers, ancestors, tribe, people of one’s town, and customs. This is the claim of the pre-Islamic age of ignorance. It is not fanaticism for the Book and the Sunnah, but rather fanaticism for one’s tribe, or for one’s father, or for one’s mother, or for the people of one’s town, or for others among the people.
Q: Regarding the group: In some other countries, there is a group of people who hold fast to the Book and the Sunnah. This group has been seized by Satan, and they have an emir. At the same time, a split occurs among them; instead of one emir, there become two or three emirs. Is this considered breaking the unity?
A: They should be advised and directed toward good so that they do not break the unity, and so that they become one. So, whoever this happens to, he should be advised and directed by his brothers, and it should be said to him: Stick to the group and address the matters. If there is something problematic among you, it should be addressed until everyone agrees on it.
Q: Does the hadith include them?
A: Yes, if there is fanaticism among them. But if they agree in meaning—even if these are in their own state and those are in their own state, this one teaches and this one teaches, and this one works and this one works, but they cooperate and there is no breaking of the unity among them—then the hadith does not include them.
