I do not understand what you mean. Why would any discussion about Christianity be inappropriate on an open forum?
Inflamitory.
Unfortunately denominational division is a sure invitation for disputes that are not constructive.
There will be no denominations is heaven, but we have them here.
Perspective of Catholics, Baptists, Methodists, and others bring disputes that should not take place. In your face hostile remarks only divide us.
I have experienced this recently during some history discussion forums. What happened in the distant past is never agreed on by opposing sides.
The U.S. was founded Religious outcasts from Europe. That persecution is possibly one of the reasons we have succeeded so well as a nation. We knew instinctively what not to do, because of the abuses in Europe.
I am not apologetic about being a Christian, but do not like sectarian disputes.
