My father is like this. He believes very strongly that he should be allowed to say anything and other people should be able to take it.

I don't really agree, personally, but I empathize with the central crux of the argument (freedom of speech, or something like that). Nobody likes to be told what (or what not) to do. But I think life would be easier if we all spent some time thinking about how our audience would perceive our words before we say them out loud.
