This isn't censorship, as you say, but as I've said, I don't agree with bans of any kind (apart from maybe ultra exceptional circumstances). I haven't mentioned infringing people's rights.
You brought up censorship - which is the suppression of free speech - which is a basic human right in most societies. But I'm not here to argue semantics.
For what it's worth, I understand and agree to some extent with the 'bandwagony' comment. People seem to really enjoy feeling outrage at the simplest thing these days.
Having said that, the things that publication said and did, and denied, and refused to apologised for - for many years. When I think of whether or not it is time to let bygones by bygones, I think of the people who campaigned for years but passed away without ever seeing justice or ever knowing if their loved ones were ever vindicated.
My own personal choice is to never have anything to do with them again, but each to his or her own.
