izy, I've not read all your posts so forgive me, but your tone seems quite, well, aggressive. You are demanding things from posters. No-one has the true facts in this case, no-one was there. It's all speculation so no-one can come up with evidence. Any thread about the McCann is fraught with speculation and amateur detectives/psychologists. It's not pleasant, but this being a free country an' all, I'm afraid there is little you can do to stop the debate.
IF's post was quite concillatory. I didn't read her previous ones, but if you just read that it sounded like she was trying to placate you. Obviously failed. But try counting to 10 before you post, or, and this might be a bit of a loony idea, don't post on McCann threads if they are going to upset you.
