Are there any 'anti-car' bicycle companies or shops? In the UK it would be a brave company that took the 'anti-car' stance when it comes to selling bicycles. Furthermore, most cycle shops, distributors and others connected with the trade are personally quite pro-car (the mechanic fixing bikes to pay for his car which he needs to get to his job fixing bikes is the classic, the accountant of one distributor driving a Porsche takes the biscuit). Then there are the customers, generally most of them are pro-car (even if necessary evil) and you cannot alienate them, can you?

Are there any companies in the bike business - large or small - that are quite open with harsh opinions about the motorcar? Or have there been, only for the business model to fail? Is deference to motoring a reality that cannot be escaped?
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.
