Very few questions can be addressed at all of Christianity without further scoping because the as far as this site is concerned the term is an umbrella under which many different groups fall, some with hugely disparate beliefs. 99 times out of 100 you will need to scope your question to something smaller than that.
But this question asks: "Can one be a practicing homosexual and also a Christian?"
Also, isn't this dangerously close to "Is 'X' a sin?", which is expressly forbidden on this site?
