Helmet fallacies

There are many logical and deductive fallacies, most of which are common in helmet debates. Here is my quick guide to them, prompted by Steven M Scharf's rather more one-sided effort. There will, of course, be bias in my selection of examples. I hope it is not too egregious. Where I have said that one side or the other is more likely to fall prey, this is based on my personal interpretation of many threads. If you think I'm wrong, or if you can think of a nicely vivid example I've missed, do tell me via the feedback link below.

We all use logical fallacies some of the time. Sometimes this is deliberate, sometimes it's accidental, sometimes with ironic intent. Use of a fallacious argument does not mean you are wrong, it simply means that the reasoning you have given does not prove your case.
