Only if we define "christian" as "a person who fancies wearing a sideways X around their neck."
The scriptures could not be more clear about homosexual relationships.
Christianity is a faith that includes many people and not all of them have the same exact view as you or I.
Therefore, I would not be so revoke a person's status as a Christian, simply because they are not in agreement with you.
Instead, I will leave that judgement to a Higher Authority.
