Why do some people some people think honest people are rude or have an attitude?

Since when is being honest a bad thing? If you ask for it, I will give it to you straight. I'm not rude. I tell it like it is and I'm direct. If you screw up it do something I don't like, I will call you out on it. I'm not going to let you get away with it. You don't wanna be called out, don't do stupid shit. Just saying. I use tact too. That's important.
