I agree ^^^
I lived in a Hungarian border town during parts of the wars there, and the secular thing was the most common thing for friends at work, restaurant owners, etc. Most of the people I knew had escaped the country, so there's a selection bias, I'm sure, but religion was barely even mentioned in passing.
People were of such mixed ethnicities from among those ethnic groups that the wars themselves seem to paint a very distorted picture of how cosmopolitan life there used to be.
The only person I knew there who had a noticeably Muslim name and gave them to his kids was from Algeria
