Keats has nothing to fear, or his admirers from those out to ridicule him.
Enh. What's with the melodrama.
Keats is dead - you're quite right he has nothing to fear. You may be impervious to ignorant opinions, and I'll rightly admit so am I, but there's a fine line between innocent ignorance and wilful insolence. The latter is the reason many forums are moderated.
So: sorry for the cynicism, but in this I totally support Golyadkin's decision (which is perhaps to be expected, since I was the one who called for moderation in the first place).
