Great points Matthew. To prevent any dandruff from that head scratching, I think that Sigismund has the benefit of having a son who is a Byzantine priest. I also think that he is in the older generation of CI posters around here, and may not think like someone who was willing to meet his wife on the internet. I mean, he may indeed have 'thought' about what that'd be like, but may never have been in the same position as holy minded, and marriage intended, trads are faced with today. So I don't think its an issue of the type of friends he's keeping, only that he (objectively) would have no need for the meeting of other trads in real life because
(1)- He has exposure to the Byzantine Rite, where most of us here are Latins; that being said, I believe the Byzantine is the most preserved of all Rites, though not without its problems and liberals. He may have no need, because of the relatively preserved Rite (please argue about this point somewhere else) he belongs to, for interaction with other like minded souls. I'd imagine he just comes on here to get an idea of the goings on's withing one spectrum of the Catholic Church. And since he's being considered for the Deaconite, it would be useful for him to have an understanding of how many in the Latin Church view the Crisis; he has a different paradigm than the majority of us, and this is why he disagrees with much of what's written here.
(2)- His age. I'm not saying someone who is older would never want to meet people (IRL) he's meet virtually, but I think there's definitely less inclination for those older generations to do so; hence the seemingly pointless, "keep the real world and the internet separate", which i think is common for many people, but abundant amongst the older generation, though not exclusive to it.
