I love people who know who they are and what their place is in life. I love strong identities. It makes relating to someone much easier. Generally, I prefer to deal with a committed Muslim than a wishy-washy Jew. With a devout Muslim, I know who I’m dealing with. I know most of their boundaries. I know what they stand for.
A Jew not rooted in Judaism, by contrast, can be all over the map. It takes a lot of effort to extract their values.
A Jew in a black suit and white shirt and a long beard, I know what to expect from such a creature. They’re going to be observant of Jewish law.
