Speaking as a Christian myself, I find that my intellectual and spiritual journey led me to this point. I find that the tenets and revelations in Christian Scripture and thought speak deeper to me on both the level of pure reason and on the plane of metaphysics than other viewpoints I have studied (various spiritualities and worldviews all considered).
It is my view that the discipline, self-denial, and self-sacrifice of my faith has made me more attuned to the needs of my brothers and sisters and thus, more attuned to the call of God.
It is my view that religion (any religion) is not meant to put meaning into our lives. The meaning and purpose is there by design. No. The purpose of such paths is to make the divine plan and the transcendent clearer to us. It is my view that (at least in the case of my own faith) religion has not failed me, but rather has succeeded wildly.
How (and IF) we reach it is up to our willingness to reach out from ourselves.
To answer your question though, yes there are many, many people here who are spiritual but not religious or are nothing at all or are categories all by themselves.
What unites us is that we see a common meeting point in our various journeys: a grave injustice which stinks in the nostrils of all persons, whether homosexual or heterosexual, religious or non. A desire to stand for the rights of our LGBT brothers and sisters in the halls of power and a will to heal and support.
So welcome Peter. Welcome home.
Yours in Christ,
