Well, here's the problem I have with the whole ritual abuse thing: it's been pretty well debunked. Back about 10 years ago, there was a whole movement that arose claiming that Satanists had a worldwide network, that they were going around kidnapping children for sacrifices, that many people had suppressed memories of these rituals, etc. A number of investigations were conducted, and basically, the outcome was that there was little or no evidence to support the vast majority of the accounts.
One of the major published works in the SRA movement was He Came to Set the Captives Free, by Rebecca Brown, who was supposedly a MD. The book reads like a bad horror novel. She tells of working in a hospital that was completely controlled by Satanists, where she, as a supposed Christian, was fighting spiritual battles over her patients on a daily basis. She speaks of a wedding to Satan himself, who appeared in a white suit. The wedding was attended by werewolves, vampires and other creatures of the night, who, she contends, really do exist. She writes of many specific events that could not have occurred without leaving some sort of evidence, but there is no evidence. Obviously, the work is absurd, and it has been thoroughly debunked.

I was a JW for almost 30 years. Many who post here were in the organization even longer. Collectively, on this board, there must be tens of thousands of years of involvement with the Watchtower. Many of the men who post here served as elders. If these satanic rituals and demon worship were actually occurring as you state, I would think that some of us would have been at least vaguely aware that something was going on. The pedophile scandal was covered as well as anything so widespread could be, yet I personally knew two JW pedophiles and a JW rapist. However, I never heard anything at all about Satanism being practiced, and I know of no other ex-JW (besides you) who claims that such things occurred. That makes the claim suspicious, at the least. The fact that you mention you are reading David Icke's works about lizard aliens and taking it seriously also leads me to question your level of credulity.
You compare my asking for proof of these claims to proving that God exists. It is true that you can't prove deductively that God exists, without making assumptions that themselves may require some proof. However, there is plenty of evidence to make a strong inductive case for the existence of God. But you are asserting that specific events (such as rituals) occurred at specific places at specific times. Surely there must have been some physical evidence? Or, if these practices are as widespread as you claim, there should be thousands of people who have clear memories of them. Some of those people would surely be willing to step forward and expose their abusers.
I don't mean to discount your personal experiences. But I get the impression from your posts of a highly suggestible person with a vivid imagination and a very low threshhold of skepticism. There seems to be little support for your contentions from other quarters. And, your accounts exactly fit the pattern of previously debunked accounts of supposed Satanic ritual abuse.
Interestingly, many of the stories being told about Satanists and their supposed evil rituals are quite similar to stories that were told about Christians in the early centuries A.D. Back then, it was Christians who were supposed to be sacrificing babies, drinking their blood, etc. I'm not saying that no Satanists ever did such vile things, but that I don't believe that it is as widespread as you claim in the population in general, and certainly not among JW's, a world with which I, and many others here, are intimately familiar.
