A lot of people in the religious world believe that by secularizing, or viewing the changes as secular, such as dropping the beard and changing my appearance, they consider this to be a fall.
A lot of people believe a lot of things. People also believe in a lot of ideas or hold tight to a lot of ideologies and beliefs.
I still believe there is a lot of truth in Orthodox Judaism, but not the whole truth. Each person has his truth that he has to discover. You don't necessarily have to mold yourself to another idea of who you are.
