If it were me and many of us on here with MEL'd beacon lighting I would assume some humanity would prevail with an apology over the airwaves.

So three possible scenarios...
- woefully unaware of both lights on and radio calls
- chose to remain silent after several calls over frequency about his own aircraft
- purposely upset and blinded all around him

Sorry but all signs point to either a disturbed, rude or neglectful pilot. Yes he is a tool.
