The entire idea is of course wrong for this reason:
My "credentials" are that I am a citizen of your much-vaunted Union, with the democratic right to say what I like about whomever I like. Those are all the credentials I need, or will ever need. It is not in your power to withdraw that right simply because you do not care for the way I exercise it.
As I myself said on my own blog when this matter was first mooted. You can have my blog when you pry it from my cold dead hands. Unitl then, I'm a free person in a free country and I'll continue to express myself as I wish, using the language and technology I desire, to say what I desire to say.
And if you don't like my views or what I say well, diddums is the only possible adult response.
