The term "normal person" is referring to your average person, and the average person has not been through such an experience. Also, the whole "once it happens to someone, they care" applies to pretty much anything. Find someone who invests a lot of their time speaking in public for any cause you can imagine. Someone who talks to audiences about the perils of alcohol, drugs, any cancer or disease - basically anything that is harmful/dangerous/deadly. How many of them do you think ever gave a second thought to their cause, before it affected their lives personally (themselves, a family member, or close friend)? Practically none of them. People generally don't care about the consequences of anything until they've been slapped in the face by it.
