Actually, my sense is that Sham has spoken honestly. Except for one thing. He has placed his thought in the plural second person so it is not owned by himself, as it would be if he said "I get irritated by honesty". Of course using circumlocutions like "we" and "everyone" and "one..." is safer, but it loses the authentic ring of the true self speaking out I think. At least, it does when I do it! :D
I think it is a question he would need to answer as to why honesty is an irritant to him.
