I have no problem whatsoever with people posting links to petitions; or expressing strong views about issues (major or minor). Why would we want to limit their free speech?
We are all of different political persuasions and those views are, quite rightly, expressed on various threads. For every right wing post, there is a countering left wing and vice versa - I see no problem at all.
I am at a loss to understand why the free expression of views is a matter of concern.
Is not freedom of speech what we are trying to find a way to defend? - people's views just differ as to the means.
There is no reason why Gransnet should be censoring free speech - and every reason why they should not.
