The problem inherent in that line of reasoning is that you say or imply that some groups are portraying cycling as more dangerous than it really is, but they could turn around and say you are portraying it as less dangerous than it really is. Whose perception is right? At the end of the day, it is a simple fact that X number of people are killed or injured cycling every year. Merely stating that, whether you compare it to other activities or not, is not fear-mongering in any sense. The reality is that cyclists can get hurt or killed; they need to know that so they can make an informed decision, just as if they were preparing to undertake any athletic activity or use another type or transport.
