I said that I didn't feel any need to discuss my posts with you, if you weren't inclined to. Likewise I don't feel any need to ignore your posts, or to become a member so I can press a little button that will make that decision for me, nor am I fussed one way or the other about replying or not replying to your posts - if I'm in the mood, I'll reply, if not, I won't. I don't single your posts out as being any more significant than any others, half the time I probably wouldn't even notice if it was you in particular I was replying.
You on the other hand have made this rather odd decision that implies you want to comment on a post but won't do so until the poster becomes a member. And yet you'll continue to respond to that poster anyway. Sounds a bit f***ed up to me.
As for Dick of the North, I guess he hasn't realised that you can't slap people on the internet. Or more likely, he has realised, which is why he confined himself to typing feeble threats with one hand while he jerks off with the other.
