Your FooReceiveServer subclasses UDPServer, it already handled the
recvfrom for you, so, this is wrong.

Moose droppings your claimed logic over the years has given us much
amusement and confirmed that you have no idea of what you are talking
about.

Most of what you perceive as logic are the ramblings of your drug adicted
mind !

Fine. Let's argue something then. Was Dresden Firebombed? Were many if not most of the people down there innocent?
Was Hanover not the recipient of White Phosphorous. Did WP quench when it's recipients dunked themselves under water, only to start burning again when the victim surfaced? Were innocent babies not burned/maimed/killed?

Moose droppings, this is one of your eternal and perenial posts that has
been answered ad naseum - go read all those old posts over many years !!

Ah, I see we are back to your other perenial theme "burnt babies". Short
answer for you - blame the parents for placing their children in danger
by voting hitler and his nazi thugs into power.

Perhaps you would like to debate the countless children murdered by the
nazi death factories - and that was long before Dresden got fried.


But what you should really do is to examine why the german people of
nineteen thirties decided to abandon all their morals and follow a
monster who ultimately used them and left them and their country in
ruins.
