You are putting a lot of stuff out here and no offence some of it would not be needed if you would take advise and get yourself familiar with our core policies. 
WRT: "Please do not arbitrarily enforce your extremely stretched interpretation without first posting the issue on this talk page." It is common practice and policy to remove un-sourced or poorly sourced material from BLP's first, that does not need prior consensus. 
WRT: "Please do not use the royal "we" when talking about yourself." We are a community and when referring to things like core policies then i will continue to do so as i think "we" agree to respect these policies as they are base on wide community consensus. 
WRT: "And what justifies deleting the ARB section?"  WP:BLP, WP:BLPPRIMARY specially WP:OR and community consensus. To go to these redacted papers and to make a list to what he has agreed on of disputed in these highly controversial hearings is original research. 
WRT: "It has a template and is currently in use for 207 articles." That other crap exist is no justification. 
WRT: "Are you going to delete all of these sections?" There is a cleanup ongoing. 
WRT: "These yearly hearings were the only information about a detainee that was produced." Some correction it was the only information that was "released". That is no justification and no indication of importance. If it would be notable than tons of secondary sources would write about it and we use their interpretations. These are complicated issues and some people have analysed these documents. Use their interpretations. 
WRT: "No secondary source is allowed in the hearing, not even the detainee's lawyer." No justification to do original research. 
WRT: "Why should it be required to find other sources quoting the same material?" It is not about "quoting" the material, it is about the interpretation. 
WRT: "Why is there a difference between the CSRT and ARB?" Not much difference.

Please get yourself familiar with our policies. I appreciate your strong will to help to bring light into these issues but original research WP:OR is a no no. These are complicated issues so feel free to ask me more questions but let me also tell you that i am only a volunteer and you can not expect me to explain all policies to you. You might consider finding a mentor. WP has a program for that. I apologize when you think my reply sounds offensive. It is not mend to upset you, i am acting in good faith. Regards.
