I say this because I am exactly that. I often cut straight to the point and can't really read the room. I think I'm helping and being brutally honest when in reality it comes off condescending or arrogant.
I heard a quote that I really like, honesty without kindness is cruelty. That helped me rethink my approach towards how I communicate.
> honesty without kindness is cruelty
That is so very spot on. I strongly identify with this, great quote.
If I wanted to go through the song and dance of buttering everyone up so they will do what I say, why bother coming up with a good idea as well? I'd just say the first thing that comes to mind. In fact, that might be why the ideas that get acted upon tend to be so bad. What's the point of the quality of the idea has no impact in it's odds for adoption?
