There is a lot of leaping at guests here but it would be interesting to know what finaly broke Dtg down.

My speculation is that the biggest straw for him would have been the almost Irish vs English threads (one of the last comment I read of his was "Did you not know that anyone English is always the aggressor?" which are threads largely played out by the same members.

I could be wrong, and there could also be several reasons but I do feel having the guest to blame does prevent looking at other possibilities.
