"Civilized men are more discourteous than savages because they know they can be impolite without having their skulls split, as a general thing."
-The tower of the elephant (1933)
Now apply this line of thought to the net.
No consequences whatsoever for what you say + audience + anonimity = instant jerk
Do you think on the long term this will somehow affect how the future generations relate to each other in real life?
Note: this is just food for thought, I'm not rooting for censorship or anything like that.
I disagree with the idea that there are no consequences to bad behaviour online.
There's still a real person on the other end of the internet tube, and your online interaction and relationship with that other person is no less than it would be face-to-face. Yes, you can walk away from an online community fairly easily, but the same is true in real life: if I was a complete jerk in RF, I probably wouldn't be made to feel welcome here. At some club meeting in real life, the same would be true.
If I want to continue interacting with people in either venue, then I have to meet certain standards of behaviour. Yes, I won't be arrested or fined for misbehaving in either one, and I can simply walk away from either one if I so choose, but this is only "no consequences" if we don't value the community and experience we get there. Since people who participate in an online community expend time and effort to do so, I think it's reasonable to assume that they value it to
some extent.
Also, I question your assumption about anonymity. Yes, it's completely possible to adopt an online persona that can't be traced back to the name on my government ID, but that online persona is still an identity. Yes, it's one that can be thrown away if you really wanted to, but then you'd have to start from scratch and build up goodwill with other members of the online community. If you value your participation in the community (and again, if you're expending time and effort to do so, it seems logical to assume that you do value it), then this is a cost as well.
