Filtering is legal in many places, and municipal governments explicitly enable this by placing bike lanes on the curbside of auto traffic. So if you live in one of these municipalities, all you are accomplishing is impeding the flow of bicycle traffic, making it actively dangerous for bicycles to follow the law, and worst of all perpetuating the so-called "war" between bicycle and automobile traffic. Disclaimer: I avoid the issue by travelling in the center of the auto traffic lane. If you don't like that, tough luck.
