Hahaha. I've never heard of this guy's blog, but if what's in this thread is indicative of it, I'm truly sad that I missed it. That "barrio" comment had me in stitches. Very glad I found this thread. I needed a laugh.
That said, the search for "authenticity" (~ no 'bourgeois' white people?) in all things, when extended into religion, always seems to produce this kind of thing. The highs are higher and the lows are lower, given how much of your own ego is on the line. You found THE CHURCH, then found out it wasn't "authentic" in the way you'd like it to be, so now you found THE CHURCH somewhere else that more closely matches what you think an "authentic" church should look like. It's not about the church; it's about you and the obsession with real religion (or politics/music/fashion/ice cream/whatever). No doubt I've been guilty of this same mindset before (maybe still am, I don't know), but I hope I've been slow and deliberate enough in approaching the Orthodox church that I've burned through this kind of anticipation ahead of actually attending any liturgies. (It'd be kind of hard not to, since my last Catholic Mass was attended in July of 2009, but my first Coptic liturgy not until August of this year. By the time I got there, it was more "Finally, I can stop wondering about this and start learning about it first-hand" than "Finally -- the most authentic, truest church ever!")
I have never heard of any prominent American or other Orthodox person converting to Catholicism. Perhaps more who are prominent in their own minds, but that's internet fame for ya. Anytime a convert from Orthodoxy would show up on any of the Catholic sites I used to follow, they'd sort of get the rock star or VIP treatment. I remember that when one of the Assyrian Church of the East parishes united with Rome a few years ago, RCs behaved like it was the fulfillment of Biblical prophecy or something. I tried to point out that this was probably more of an indication of the dire straits of the ACoE than of the inherent strength in Roman theological positions (they've got us all beat in pure numbers, that's for sure), but was mostly ignored or told to stop being a wet blanket. Similarly, I have known people who take the words of James Likoudis (probably the most famous EO-turned-RC, in terms of visibility if not weight of opinion) as though they were not only gospel, but also somehow represent faithfully the position of the EO.
In other words, wherever you look, there's a whole lot of wishful thinking going on...
