@maxdancona,
Which people are you referring to?
If it's in religion/religious based threads, don't pay it much mind. Some are perhaps just starting out on their Christian faith journey. Others may be Christians from day one. Either way people are people and as such are susceptible to sin and error. If they are truly penitent and remorseful, seeking forgiveness from their God, then that is how they live.
If the reference point is those claiming to be Christians in other threads, does it matter? Keep with the thread topic of that is what got you into the thread.
In any case, so you really want to devote so much energy to such things as their imperfections?
As for me, I don't consider myself to be a Christian, even though I was raised primarily Methodist. (I was also raised partially Jewish). That to the side, I have a belief in some sort of higher/greater power-essence.
So, are you addressing just Christians or all God believers?
