In this thread I think you'll find I've only ever responded when people have waded in with the usual 'you'd be an idiot not to wear a helmet stuff'. Elsewhere on the forum you might have a point.
Interesting point about people wading in.
The truth is many don't. They post elsewhere on the forum and without knowledge of this thread (and no chance to read 20 pages let alone 300) their post is moved here. Many are simply telling their own little story which under normal circumstances might be countered / debated and would then die a death. However its placed into this shark tank of a thread, they suddenly get alerts and its then fight or flight.
The same happened to me. A post of mine was placed into a previous helmet thread without my knowledge. The first response from a regular poster was 'we have a live one here' and so it started....
The most recent example was keithmac who a few weeks ago posted an innocuous post....it was moved here and the whole thing kicked off again.
Many forums don't entertain this subject in a thread, for the very reasons as displayed here. People become entrenched and issues arise. I'm of the firm belief this thread should be closed down as the personalities and ego's from some on here have developed to such an extent they literally think they run the place.
