I want to take a kinder view of your comment than some of the other replies currently, in that there's a kernel of truth in what you say. I would rephrase it though, in that it's not that cyclists are inherently dangerous, it's more that mixing modes of transport that have vastly varying capabilities is dangerous. Any time you have vehicles of vastly variable mass and capabilities sharing a road, it's inherently more dangerous than if they were to be separated.

That goes for cars and bikes, and cars and pedestrians, and bikes and pedestrians.
