Kristor and Joseph at Arimathea have provided a perfect example of what I mean by language I can read and mostly understand, but am unable to speak except for a few awkward, halting sentences.
I intend no disrespect when I say this. I understand enough of what they're saying to know that it isn't just obfuscated gibberish and that something important is being discussed. I'm simply not competent to judge whether what it is being said is correct, or to articulate a meaningful, worthwhile response.
Nevertheless I find it pleasant reading.
