I don't know whether to laugh or scream, reading some of the responses one here. Am I on a different Gransnet site from some of the posters? What I'm reading here just doesn't match what I see on the political threads!
It's just that some of the most stinging, critical replies to the OP on this thread seem to be from posters who are amongst the most vociferous on the politics forum, and whose posts regularly include the very things that they are criticising here.
Is it just me?

Anyway, in answer to the OP, I imagine that as other posters above have said, it's not necessarily lack of interest in politics that stops a lot of Gransnetters from posting on the politics forum, but rather a fear of being verbally attacked (or whatever the written equivalent is), as regularly happens, with people on both sides of an argument being equally guilty of this.
That said, I've known a lot of people over the years who say they have no interest whatsoever in politics, though many of them had very strong views on issues that rather belied the claim!
