Not an insult, Iains. A perfectly justified inference. If you throw out a challenge of this nature:

"How many reading this have watched no porn on their own computers?"

...then it's clear that you're trying to exonerate Green (and presumably yourself) by making the use of porn on computers as anodyne and normal a thing as eating your cornflakes or going for a wee (shame that you caused a mini-uprising of Mudcat members who are totally not with you, eh?). In any case, as you clearly think that using porn is a perfectly fine thing to do, how is it an insult to suggest that it's part of your personal repertoire? As a matter of fact, if anyone's insulting anybody, it's you suggesting via the above remark that "we're all at it." But we're not bitter. We're just unsurprised, knowing you as we do, that you have shown yourself to be completely out of touch with the overall ethos here.

Yours amusedly, Steve, stone cold sober mudratter, come up and see my computer any time.
