Are they hostile to car owners or is it the car dependency enforced via city planning / infrastructure? I almost always see the latter but hear the former as criticism which is laughable.
I think it's somewhat of an optics issue, but it is very hard to find walkability communities online that aren't using terms like "car-brain". I know that these terms are targeted at a certain type of car owner, but without being familiar with the car-free community this is not always clear and can be a turn-off to car-owners who may be curious about learning more.
