When gulliver1 sticks to "playing the ball not the man" (as the Ed has encouraged us all to do), then I'll do likewise with him.
Indeed I do just that for just about everyone else on this site - including, for example, posters like TTT - with whom I actually have far more differences on policy and politics than I do with gulliver1 - and so we maintain a grudging respect for each other, I think.
But I refuse to play with one arm tied behind my back, so I give as good as I get with gulliver1 and even occasionally "get my retaliation in first", as is the case today with his particularly repellent gloating at the plight of schoolchildren.
