I am reminded of the Spike Milligan's remembrance of a Public Toilet attendant defending his job from ridicule.

"It may be crap to you but it's bread and butter to me"

I think people should speak plainly though and readers should remember what they are reading is the opinion of the writer.

It better to know the true feelings of someone than have it watered down or deferentially filtered to the point where you don't really get the meaning of what is being said.

Naturally it doesn't follow that you have to agree with the opinion but your response will also be an opinion (hopefully and informed one).

Democritus says :

Nothing exists except atoms and empty space; everything else is opinion.

But that's just his opinion.
