Read and inwardly digest the above rules of engagement here on Pprune. There is no 'right' of free speech here; this is Danny's front room, and you behave yourselves as he demands when you accept his hospitality. There are many factors at work in a site of this size, and we are neither able nor willing to explain all of them to you. You have to accept the place as it is. That includes the fact that certain organisations and individuals are persona non grata. The explanation I or any other moderator may give may well be a gross simplification of the facts; in essence, the reasons for any loss of appearance privileges here are none of your business.
Anyone who has a problem with Danny's house rules are, of course, welcome to take up the argument with the man himself. Until and unless he changes those rules, I will apply them as he dictates.
