I think that such childishness becomes downright funny when they run too quickly to 2 Timothy 2:25-26 in an attempt to blast someone who is actually being more reasonable and ultimately more gracious than they are. Why do I think this is funny? It's because Paul wrote 2 Timothy 2, and he still wound up offending the Corinthians. (Do you suppose they said "Hey, fellow, you need to read 2 Timothy 2!"?)
I should have said "he still wound up offending the Corinthian church members."
(For what it's worth, the churches which I have noticed as being most profoundly offended by doctrinal confrontations are Methodist churches and dispensational churches.)
