Not usually. People who do that think they're saying something that someone needs to hear, but they're usually either wrong, or saying it in a manner that does make them an asshole.
I disagree. Most people don’t want to hear the truth and will take anything they don’t want to hear as a personal attack against them.
I’ve seen it time and time again.. and then pushed out on social media to make the person that said it look like the bad guy...and since it’s usually one person against another, it’s impossible to defend.
This is why when the technology gets cheap enough, I will have a secret body cam on me at all times.
It’s already been proven many times that privacy no longer matters. Hell, a guy got an entire basketball team taken away from him based on private conversations.
Speaking of the truth: Sterling lost his basketball team because of private recordings of him being a racist, not hearsay. Then he proceeded to dig a deeper hole publicly. That is: a lapel-camera would not have exonerated him.
Here's some advice, since you think you can take it. When striving to correct others: (a) Make sure you're actually correct (b) make sure you're doing it to reach a common goal, rather than to uplift yourself and (c) understand that a defensive reaction is not a weakness, it's an entirely normal human reaction, and try to empathize with the person as you deliver the hard news.
A lot of people think that others don't want to hear the truth, but it's not that. Most people want to know what's going on. What most people don't want to endure is the embarrassment of being wrong in front of someone -- which is an entirely different thing.
People get corrected on stuff all the time and take it in stride. It's when there is a blow to their ego or you're actually wrong that they get upset. So, you need to either make it clear it's not about them in particular (it usually isn't, hence the "common goal"), and even if it is, you need to make sure they know it's about making them better, not tearing them down. And, you have to be willing to consider counter-arguments -- that is, not pretend you are the sole arbiter of truth.
Bluntly stating an uncomfortable truth (or opinion!) with no quarter is not what people who seek the truth do, it is what people who want to be in control do.
"This is why when the technology gets cheap enough, I will have a secret body cam on me at all times."
So rather than develop the interpersonal skills that would allow you to say those kinds of things without sounding like an asshole, you're just going to secretly record everyone you run into (which is something that will solidify you as an asshole), and have this video record of you being an asshole to people.
You tell someone something they don't want to hear, but need to hear, and you are now known as an asshole.
