Nope, I've given you the argument. Ad nauseam, actually, pretty fully as it happens over lots of posts, and you have my Guido- and grauniad-free opinions, as comprehensively as you like. I'm sorry that you feel so embarrassed. All-in-all, it hasn't been your finest day. Has it, Iains? Better luck tomorrow!

By the way, my offer to you of free proofreading has expired. It troubled me, on reflection, that, in your case, there was so much to do. Details on request, going back for as long as you like. But if you'd like an obligation-free trial, just let me know. Obviously, as is the way of things these days, I can't promise that you won't be subsequently bombarded by my ads. Aren't Google bastards!
