Let’s speak about Amazigh Tuaregs Berbers Sahrawis Nubians. Completely Arabized culturally yet still hold the distinct DNA make up of a different people.

What’s so wrong about maintaining the cultures of your ancestors or at least learning about it. Learning about culture is not counter to your religious beliefs. When a religious belief wants to stop you from discovering other aspects of who you are there is something wrong. Knowledge is not limited to what you want it to be and putting people inside of a box for your comfort is not doing anybody any favors.
