Yeah perhaps you're right.
No kidding, particularly when you get little twerps talk to you like your a bag of **** on here. You have to just brush it off as its that or get wound up about it. All said and done, 90% of time when people act like morons on here its because hidden behind a monitor - face to face people tend to give what they say a little more thought or wouldn't dare say anything of the kind in the first place.
Yeah, it's a shame it works like that, but that's the way it goes (not just here though). I always try to be 'charitable' towards newbies because I was one once too. I think it's best to post nothing if you have nothing positive to post, and simply withhold as it does nobody any good and looks bad on the community as a whole.
However, idiots in the motoring forum are fair game TBH.
