You are supposed to sue if you are seriously injured and have no other choice really. That's what insurance is for. Ignore the people who say otherwise. I tell my own parents that I would sue them if I slipped as long as their insurance protects them.  I expect they would do the same.  

I'm not talking about litigiousness here, but fair compensation.  Ideally you want to minimize the lawyers if possible - who poison the process. What kind of friend or family would not let you sue their insurance company if you were seriously injured by their steps? 

The mobs of strangers on FB are the ones I don't care much about. I try to avoid giving them reason to sue me by not inviting them to my house.

Having said that, it does not sound like you were in a completely rationale state when you were ranting on FB.
