Please, DFTFT and don't quote that SOB - whether it posts as sherp, or SanSouci, or Raisuli, or Laguna (all the same person, and those likely aren't all their multiple trolling log-ins).
Telling a troll (if he is a troll) why he is wrong is not feeding him. Reacting emotionally by blocking him or shouting names at him, feeds the troll and gives him fuel. Getting mad and reacting..well, you let the troll win.
