As far as I am concerned it is not my place to "tell" you what is what. Finding out is part of YOUR personal journey, and we all take different paths and/or travel those paths at a different pace.
I was born in secular family. We rarely spoke about religion. Officially I still am a Lutheran Christian. I think secular background is good. Often I see, when people are grown in some religion, they can be inflexible, or they may think that their beliefs are self-evident.
If I could have chosen... I don't know. None of the major religions seems very good. I'd probably choose to be born in a family without religion (it does not mean atheism), or with neutral religion like our State Lutheranism. I imagine it could as well be Jewish religion, or Hinduism, or Sikh.
Love is more important, than what special religion you are born into. Without love, what matters if you were born in finest religion? What matters, is mother love.
I feel that secularism gave good background for seeking and studying, and comparing between religions and paths. No one was forcing me.
