I was referring also to Ms Altenhofen, who like many cyclists who write in to the paper clearly feel superior to people who use cars for transportation.  No, Ms Macarelli's daughters don't need to take kids to daycare, grandma to the doctor and commute 30 miles to a job now, but someday they may.  Maybe they won't be able to brag about their "one car lifestyle". Will mom look down on them at that point?  

I have no idea about 'doth protesting too much'.  I'm expressing my opinion.  If riding a bike fits in your lifestyle, go for it.  But don't disdain those who don't have the health or lifestyle that enables biking everywhere or even anywhere.  When people talk about how virtuous they are in their "happy healthy lifestyle" and "not contributing to global warming", that's what they are doing.
