I delete the emails once I've read them or not as the case my be. Some simply complain about language used but they generally refer to racist undertones and such like. I used to explain that views expressed are generally genuinely held views of contributors and that the forum is open to anyone who wishes to take issue with or challenge them. I suspect a good few, purporting to be from different objectors claiming to be drivers or relatives of drivers, were in fact from a single source as similar terminology (notably bringing the industry into disrepute, etc) was used.
