Yes, he is in a rage. His daughter is missing and he thinks someone took her. Inappropriate? You bet! Especially when he has people doing/saying what they're doing/saying, including his own "family". I'd like to see an instruction book on how to behave when your child is missing. I know that I'd fail the final exam miserably. I'd fail in real life too and the Internet would be raking me over the coals too.
I posted this previously:
[In part] We each use our own backgrounds, geographic locations (which includes the social norms in which we live, work and play), education, personalities, psychological make-up, social-economic history/situations, mental acuity, etc etc etc to draw conclusions.
Drawing conclusions without applying the fact that we are all different is a big no-no. MOO.
Of course this is just my opinion, just like it's your opinion that "This is a fact backed up by evidence, not an opinion."
