If there's a bike lane, use it.
No one died to have bike lanes put in, but there has been a more or less constant backlash against them ever since the first one was painted down. The best way to fight back is to utilize them and utilize them properly. Riding in traffic might be easier and more convenient, but that just provides ammunition to the anti-cycling people: "We give them bike lanes and they don't even use them!" Don't be that guy (or girl).
