The word “honest” is used in strange ways these days. When someone wants to say something cruel, they justify saying it by using honesty as an excuse. “I just have to be honest.”
Those who practice “radical honesty” often seem to use that to say whatever mean thing comes into their heads. Do those same people also say all the good things that come into their heads? It doesn’t seem like it. To me radical honesty would involve telling people I see how much I like how they’ve done their hair or how beautiful their skirt is.
Honesty cuts both ways, in my opinion. If you want to be so honest that you’re going to tell someone that their artwork is childish, then you also have to be honest enough to tell someone when you are jealous of them and wish that you had their drive.
