So have most of us. I try not to get personal on here, but I think the poster you are responding to thinks the rest of us are somehow ill-informed and/or stupid. The latest is that we have only just become aware that this country has an immigration problem. He also likes to lecture us on what's happening in Europe/the wider world (presumably from behind his keyboard in Cardiff while some of us are living/working 'out there' on a daily basis).
To be fair, most I would just ignore. At least he is irritating enough to provoke a response!
