Definition of the term arabize

There is a historical malaise that disturbs my logic in this question of Amazighité/arabo-islamité. Islam arabises the imazighen (,Berbers) it seems, and the kabyles are imazighen who refuse to arabise, it seems. But it is claimed that the Kabyle are not only fervent Muslims, but defend and enrich Islam. Or maybe all this is true, which makes the Kabyle the biggest betas in the world, since they cajole what would surely Arabize them. Moreover, I wonder why Islam has not Arabized the Kabyle for 15 centuries in order to Arabize them as quickly as possible?
Or maybe the Kabyle realize that Islam is Arabizing in this land of Allah and flee from it like the plague because they don’t intend to Arabize themselves any time soon.
Mathematically speaking, the problem can be summarised as follows:
– It is common knowledge that the Berbers have been Arabised for centuries by Islam.
– It is common knowledge that the Kabyle stubbornly refuse to be Arabised.
Would the conclusion be: the Kabyle are Muslims
Or the Kabyle cannot logically be Muslims.

My personal conclusion: the Kabyle who really don’t want to arabise, don’t take the risk of becoming Muslim. And the Kabyle who are ready to arabise without regret become zealous Muslims, in order to arabise faster and get it over with.
 Ariless.
