Are there any 'anti-car' bicycle companies or shops?
Well, there's the Cars-R-Coffins website, but i don't know of any shops that are actively anti-car.

It's pretty counter productive, and even if you push the green dream pretty hard, it's generally recognized that positive input is better than negativity. 

For example: Most people respond better to, "I ride my bike because it's good, cheap transportation, and environmentally sound." than they do to, "Stop killing the planet with your 6 mpg Hummer H2, you inconsiderate #$@%!*..." 

There are advocacy organizations that will push the line pretty hard, but retailers and wholesalers have to maintain balance a bit better than that.

FTR, I don't think you are insensitive to this, i just think it's an answer that you pretty much stated in your question.
