In defence of Mart:
1) Mart was not being unnecessarily nasty to an individual, which is the main gripe I, and many others, have with many internet forums.
2) A rational, intelligent person would not think that a person's performance on a game show would provide a person with cause to launch into a vicious attack on someone they've never met. However, that same rational, intelligent person might well feel that it is perfectly reasonable to criticise the person who launched such an unnecessary attack.
I see no double standarRAB here at all.
