Yeah, I think we're talking about different groups. I'm talking about people who self-identify as "anti-car". I've never heard of anyone who uses "anti-car" as a derogatory term for others, but I wouldn't be surprised if they exist somewhere. Personally, it seems unreasonable to me to define "anti-car" as "supports other modes of transit"; "anti-car" by my definition (which I think is the main definition) requires emphatic opposition to cars.
