Yeah it drives me nuts too. Basically insinuates that if you aren't starving in Africa then you should keep quiet. See it a bit on mountain-bike forums. Oh you shouldn't be complaining about your $15k bike because first world problems etc.
NB. I do not have a $15k mountain-bike! Maybe if I added them altogether... N+1
Labelling it as such is just an acknowledgment that it's a pretty inconsequential in the scheme of things. It's not matter of putting up and shutting up, it's just an acknowledgment that's all.
That may be so, but on another forum, this time golf, people will discuss/argue the merits of a particular golfer and usually someone will chime in, oh what have you achieved in golf compared to Tiger, what do you know etc, how are you qualified to say that...
That's the whole point. If the forum was for Tiger Woods types only it would be a very quiet forum!!
