And there are "denominations" that embrace the leader nailing every 12 y/o girl in the congregation. Just cause someone claims to be "Christian" don't mean they bear even a passing resemblane to the actual faith....
I have no disrespect for you and your faith.
As a matter of fact, I believe that Christianity was instrumental for creating the Western institutions we enjoy today.
But it is also true that there exist thousands of sects of Christianity that choose to emphasize, stress, or ignore a variety of parts from the Scripture, and reach radically different conclusions.
Since I am not myself a Christian (and do not hold the belief the Gospels hold the actual words of Jesus, or are divinely inspired outside the extent any book may be divinely inspired), I cannot speak as to 'which' group is more true to the actual intent of Jesus. However from the point of view of the history of Christianity as a non-religious discipline, all of those groups should be defined as 'Christian' if only due to their tentative inspiration by the 'gospel'.
