Of course _their_ usage never impinges on anyone else's. It is only the usage of this mysterious 5% that ever effects anyone else. They want a pay as you use model because they don't use it very much, but they also want to ingnore that the bulk of cost of _their_ conection is the same regardless of how much they use it. This reality does not fit their desired belief, so they ignore it.
This is not intended to be personal, I merely use these two as examples because they have been vocal on the issue. It could be any 'they' that holds this same 'mythical' belief.

I would say that you have got an idea into your head and nothing will persuade you to change your mind.
The train and the gunman analogy is valid because a few users can affect the service of many. The two gunmen are grabbing the majority of the seating capacity because of their actions. If ten 1Mb users are online using p2p and maxing out their upstreams (there may be very little us of their downstreams) then they will have saturated that upstream card. The upstream card has a capacity of probably less than 2000 kbps after DOCSIS overheads are taken into account and the 1Mb users at max are using 256kbps. 10 x 256 = 2560 in my book and that is more than the card can accomodate so there is already a slowdown in performance for those ten. Along comes anothr 1Mb user who just wants to download a large legal ISO from a website. He can not achieve the 1048 kbps download that his connection is capable of because his upstream ack packets are slowed down because of the upstream being saturated. Another 100 users come on line at any speed and wish to browse, download or watch streaming video. What will their experience be like? Everyone on that upstream card will have a performance which is slower than dial-up. If the ten p2p users then go offline the other users will more than likely enjoy a normal experience.
Bandwidth can be said to be the amount of data that can be passed along a communications channel in a given period of time (look it up on dictionary.com). If the given time is 24 hours then it should be easy to see that a relatively small number of customers on the fastest connections that are using them to the max 24/7 can pass a hell of a lot more data than a very large number of customers that are only on for short periods and may be on much slower connections and just doing a bit of browsing and e-mail checking.
