TU731..- Not completely true. Modern can mean one is more in tune with technology. Maybe some look at it bad, but this world is here for us to use for the good. So long as we are doing so, then modern life isn’t against Halacha at all. Judiasm is amazing not just for it’s survival, but also for it’s diversity. Modern is not really a negative, just a different type.
Just to be clear, I’m not saying all modern concepts are good at all. Only if one is truly living their life according to Torah and Rabbinic standards, then modern is just a description. Like working, black hat, BY, MO, etc. What is really needed is a book on every type of Jew. There are so many groups, and groups within groups, that there seems to be a different type of Judiasm for everyone Jewish.
