Fair enough - being nice to people isnt a bad thing. In my case Im just a glaswegian cunt so what can I say 
Having said that - in this case he was imo obviously a waste of space from the first post and certainly from the passive aggressive sarcastic replies
- his first 2 posts were questions
- the q here implied previous knowledge of the scene
- it was a q he could easily have answered with a bit of reading so basically he didnt want to waste his own time but was happy to waste ours
Basically I doubt he would ever have contributed so was laying himself open to whatever abuse people want to throw at him.
The other point worth making is that after a few posts he flounced off in a burst of righteous indignation. At the end of the day you get all sorts of people on here with as many different backgrounds as u can imagine. Some are aggressive. If you cant deal with that you arent going to be much use so again, if it hadnt been this thread it would have been somewhere else I think.
From a personal perspective, I dont mind if people read without contributing (though admin has recently clamped down on this) but what does piss me off is people who ask questions without contributing, especially if what they are asking is already available. So I tend to get more aggressive in those cases. Ither people will have different views which is fine too, but again that is the nature of this place.
My (extra) 2p fwiw
