You are right in much of what you say. However, you are also right in that much of the loonier aspects are fear-based. Where there is fear there is not faith, and vice-versa. Anyone who really knows scripture and really knows the Father and the Son in the Holy Spirit knows that the essence of Christianity is summed up by Jeshu in Matthew 22:35-40. In short: love. If what you believe, think, say or do is not coming from a place of love then no, you are not being a true Christian in it.
