Whilst I'm in no way defending Walter [and in fact am flabbergasted as to why he hasn't been banned], for me at least it's clear his outbursts are fuelled by booze and at least he has come and apologised. OK, it might not really make up for it in the slightest but it's a start. I think this constant flaming even before this "incident" was a tad out of order - after all he's run his team at least 1000x better than several other LFS teams I can think of [I'll let you name them] and, whilst he can be a bit of a plonker sometimes, at least he's not going round spamming the forum with complete crap like some people are.
Firstly, the mods need to ban him as a punishment, and secondly people need to stop going into FLAME WAR mode at every opportunity to satisfy their major e-egos.
