I hate driving a wedge between denominations but one of my Orthodox friends unironically believes >pic related. Besides having some preposterous elements (like Catholicism being put on the same level as atheists, even though Catholic theology is mostly similar to Orthodoxy), the scaling is cited by him as an excuse for unchristian behavior. My friend's method of "proselytization" to everyone is being extremely obstreperous to everyone he meets, shitposting constantly to get a rise out of people and to boost his own ego. He's completely unconcerned about driving people away because of the way the "scoring" works, as he thinks it inconsequential if someone is driven away by his personality into becoming a total degenerate instead.
How should I talk him out of this or is he deluded enough to be a lost cause?
