Actually, I pretty much do think that. Though my true feelings are a bit more nuanced. But most motorists easily fit the bill. After all, some folks live within easy cycling distance of work and amenities (sometimes within just a few hundred yards), yet they still drive. These lazy people sicken me. They are often so unfit and there are so many of them that they increase my health insurance costs, they use up our natural resources and pollute unnecessarily, they clog up the roads and create vast parking lots in downtown areas that are essentially mini-deserts - wastelands of asphalt. It's disgusting! At best, these folks are a drag on the system; at worst, they are a cancer.
And when it comes to living close to work, no one's forcing anyone to buy a house - there are many rentals very close to workplaces. I just finished renting in a house close to downtown - stayed there for 2 1/2 years - finally found a house for sale at a reasonable price and where I needed it to be. Anyway, I live in the US, where it is mostly true that all car drivers are obese yobbos and yobettes with a vast sense of entitlement and/or a lot more money than sense. Maybe that's not so much the case in the UK, but my opinions surely apply to many - perhaps most - drivers there too. I'm not suggesting everyone meets my characterization, but too many do.
The problem a lot of people are having right now is that we are living at a time when suburbia and home ownership have been pushed, for 50 years or more, as the utopian ideal. And it would have kept being so if the economy hadn't tanked. Now those who bought into the ideal are stuck way out in the Styx with petrol prices going through the roof, with more money owed to their mortgages than their houses are worth, and therefore with no way to sell. It is not my fault that they couldn't see that they were buying into a scam - a housing pyramid scheme. I could see this problem coming back in the 1990s, and I'm no economic genius, so it's not as if it was some difficult-to-see issue. I decided back then that buying into suburbia was a fools game.
Anyway, getting back to the OP's post, I think there are two yawning gulfs - one between cyclists and non-cyclists and another between cyclists and motorists who own a bike. After all, many motorists occasionally cycle and therefore believe themselves to be cyclists. These are the same sorts of folks as those people who volunteer to pick up trash in the park for two hours and suddenly think they're environmentalists.
