The verdict:
TCBB was a good idea towards a good cause, but people like Grumpy and Bisjac (who of the latter I still retain respect for) are low enough to cut it out at the knees: by flaming an anti-flame clan.
I guess since people are considered oh-so-cool by how nonchalantly harsh they can be on these forums, there's really no point to fighting back.
Looks like the RTB forums is where I'll be now, more frequently than this...place.
