I wouldn't trust "brutally honest" people.
From my experience they're lonely people who try to "save" someone or "show the light" so you'll be drawn to them instead. They're creating anxiety, worries and dread of others to get more attention from you.

If you have bad feelings about those people, I'd advise to steer clear of them. They seem to only annoy you, no point in getting closer, as one tried to steer you away from your other friends.

They're using "truth" and "savior" attitudes to give you a feeling they're safe, but they're actually trying to put you on their terms.
They are not honesty and they are not truth, so I know what you mean when you sense arrogance.
