Honest words can be misconstrued as being rude. I think it just depends on how one feels at the time.

Being honest means having to be blunt sometimes. Being blunt is, quite often, considered rude.

I find, IRL, most people have difficulty expressing truths (for whatever reason) and therefore, end up "beating around the bush," so to speak. With some such people, honest and straightforward words often shock, and give rise to an impression of rudeness.
