What a sad, pathetic life he must lead--to feel the need to excoriate fellow Christians. Thank goodness our Lord has much mercy...and justice.
I used to think so too, but after an incident in 2004 I realized that it is a combination of ignorance and “false news”.
In 2004 I visited Athens for the first time and went on a tour of the Acropolis with a guide. There was an elderly Florida gent who came along (I didn’t know him prior to this) and half way through this he was asking questions about how this and that was in the Da Vinci code. The guide patiently explained to him how this was wrong.
I then chatted with him during a break.
Still didn’t convince him. He gave me his email.
After 4 years of delicately pointing out the errors to him here and there, he finally started reading for himself and realized the false information fed to him. But it took 4 years.
We have a lot of implicit bias in what we have heard.
