I myself know of a few people who have withdrawn from the field for that very reason. Though there are ways to protect oneself and ones children.
The following is from my personal perspective/experience - the core of the issue is usually not from the entity itself but usually of human origin. In terms of risks and protections, once one takes measures to protect oneself, a separate measure isn't for each entity/spell. Also, an entity attacking someone like that isn't free from risk to itself either but this itself can become its own discussion.
