BJörn, if communicating on this list in a civil way is too hard for you, I suggest you leave the whole communication business to someone else.
Jayjg, what a stunningly insightful remark, I'm amazed. However, I think you are wrong. If communicating on this list in a civil way was too hard for me, I believe I would have told you to "Fuck off" or maybe "Go fuck yourself." Since that is not the case, communicating in a civil way is obviously not too hard for me.
If you imagine that civility consists of refraining from telling someone to "go fuck themselves", then there's little I can say.
I'm more interested in discussing why it is a customary condoned practice for admins to block IP:s when they have no idea how many people their block might effect and when they haven't even done the most basic checkup (whois). I think that it would be good if those that do it is told that it is unacceptable and irresponsible. Discussions about my character does not belong on this mailing list, you can instead use my email address if you wish to go on.
