I'm supposing some people might be more anxious about it than others, and in different contexts. If you see a lot of stuff in the news about people saying things you might have said and getting hounded for it that might make you super anxious - you don't know the etiquette anymore!!
I mean people get anxious about getting robbed when they read a robbery happened, why shouldn't they get anxious about having their life destroyed for something they said if they read someone got their life destroyed in that way.
