Mentch1- Religiosity is a very large spectrum. The people you know who call themselves MO and the people I know who identify as MO can have vastly different levels of commitment. But as far as my experiences in a MO community I have found that a lot of my friends, teachers, and classmates had a strong commitment to halacha. They may not keep every single chumra but they do keep most halachot.
As far as my screen name- I think that it represents what modern orthodoxy is all about. I live as a Jew in the world around me and I am able to follow halacha while still enjoying the positive parts of secular culture.
