 consultant and lecturer in the area of his expertise, cults (bolded words add nothing)
This seems pretty much ok, this is what he is... correct ?
 he is commonly referred to as is imprecise, especially given the quotation marks (and avoids ""exit counseling""/kidnapping controversies)
This is better version of he claims to be
 he maintains an informative database etc inserts unnecessary opinions (see WP:Weasel)
Respectfully i disagree... this is what it is, we can exclude the term informative and just database, this is one of his works.
 he also owns cultnews.com and changing ""blog"" to ""web site"" obscures that these are self-published and not WP:RS
This page is about a person who control that site, this link is a must in this page, cannot be avoided.
 the fact that he is an expert witness in some courts is inarguable but the added phrase in relation to his expert knowledge etc adds nothing
Agree, this line can be removed.
