Emotion driven posts you mean like those suggesting one should carry a gun to defend themselves against a low probability threat, one they can in fact eliminate by changing their bike route, at which time when the threat occurs the gun will probably be ineffective because the gunslinger just crashed off a bike going 20 mph? Like those posts you mean?

Keep the gun at home. Carry, on your person, in an easily accessible holster, trained and ready to draw, when you must go to a crime infested area like downtown after dark. But when riding? Are you serious???? There are so many things wrong with that, already pointed out. You just won't listen.
