I will say this: What I have read so far is the first page that you linked too. I have not read all of the sub-pages after that, although I may read some more later when I have more time.
I'll address a couple of the charges they made:
Of course, there is no easy way for me to know exactly what they are talking about here, but are they saying that he admitted to lying and the other things
when he was a Scientologist? If so, what does it mean that he once had such a high position in the Church?
Wiki page on Mark Rathburn
Again, they don't tell the reader what it is that he contradicted himself on.
Is it that he once publically espoused the Church's line and now says something different? These are very vague allegations, long on character assassination and short on specifics or evidence.
According to
Wikipedia he was formerly the "chief spokesman of the Church of Scientology.[2]" The chief spokesman! Why doesn't the rebuttal mention this, or the former position of Mark Rathburn either?
I'll just quote what it says about the circumstances of his leaving the Church:
I couldn't find confirmation that the judge ordered the Headleys to pay $40,000 to the Church to cover its legal costs, but the Church did win
that lawsuit and its appeal.
Someone pointed out that because the Church pays its SEA org members so little ($50/week) despite working 80-hour weeks, they qualify for food stamps and other government assistance. Yeah, taxpayers make up the difference. What do you think of that?
