I can kind of guess what they may have meant? But it's hard to follow the thinking in sentences and across posts. I've just reread the one of mine that was a response to, and think it may be a case of misunderstanding compounding misunderstanding, compounding... but dunno, really.
I know I keep going on about it, but this is what makes the TRA cause so unconvincing. I really think we try to understand what they're saying, but it's like nailing jelly to a table. And then our attempts to understand or challenge what we've understood in turn are jellified - "Nice essay, Jo!" becomes "hero worship", and pinpointing a potential discrepancy becomes "identifying and distorting a simple point".
Time and time again the visitors here drive us to the same conclusion: it's hard to explain the inexplicable and justify the unjustifiable. Grammar itself seems to collapse under the weight of it all.
