"Can it be explained why my request that any editing comments (especially those containing only personal opinions) are not inserted into my posts without my prior permission is ignored?"

....see above. NOT ignored, just not accepted. Editorial comments of that sort BELONG at the point where the editing was done. It makes sense to put the comments there, whether you approve or not!

Do you judge that editing comments of that sort are required, belong and make sense ONLY where they are inserted into my posts? If censorship must take place - why do you consider that does not then make sense to place all editing comments where they belong?

This where any form of imposed action has be judged to be required and to enable all poster to make an informed judgement on the true nature and level of censorship on our forum.

Why do you consider one to be good idea and the other to be bad one?

I have little objection to editing comments of explanation being inserted into my posts. What I have objected to are personal views and judgements being inserted into my posts - under cover of this and not refreshing the thread. When if these need to be posted - they should be contained in conventional posts and refresh the thread - like the posts of every ordinary poster.
