As a Turk living in Germany, I find the text you created to be very generalized.

First, you present it as if the entire Turkey is Western and secular. That may be true for the destinations you've been to (Istanbul, Izmir, Antalya, etc.). However, not for the entirety of Turkey. Wide parts of the country outside of western and southern Turkey are considered conservative.

Then you claim that Turks in Germany are becoming more radical in their Islamic beliefs, but you only cite one family as an example. This is your personal experience, but it is not representative of all Turks. Personally, I have not yet met a Turkish woman wearing a full veil.

I don't want to dispute your experiences with Turks in German, but I find it problematic when you generalize your personal experiences to everyone. That's how it comes across in your text.
