Biblical Christianity is not about following rules. You can 'try' be a 'good' Christian and fail. I know however that some churches do teach that you are a Christian based on what you do, rather than what you believe, but I'd suggest people read what the Bible teaches to understand Christianity. The Old Testament was about following the Law given by God. In the New Testament that was replaced by grace.
I fully accept and agree that there is much in the teaching and practices of the church over the years that has been hypocritical, unfair and 'un-Christian'.
