calling Franko a "muppet", (something he regularly resorts to whenever someone doesn't agree with his POV, but never seems to be moderated for.)
Subjective, really. Muppet is pretty innocuous. If somebody called me a muppet, I'd be pretty unfazed. Personal insults are a rum do, but you have to keep a sense of scale.
When stuff gets
nasty and people get upset, then moderation comes into play. You'd all be complaining about censorship like it was going out of fashion if we cracked down on the slightest aggravated exchange.
If one takes offence at being called a muppet by a complete stranger for suggesting it is unbelievable that someone actually uses a "clean" system, then they should also realise that it is equally (if not a lot more) insulting to have your honesty questioned by a complete stranger.
