I hate people who refuse to admit they're wrong
Could you explain further what it is exactly about these people who refuse to admit they're wrong that makes you hate them?
They say they are right until the end.
It's okay to feel that way. It's annoying when people don't admit they are wrong.
People who can admit that they're wrong is always better. Being stubborn never helps.
You can be frustrated with people, especially if they keep saying they're right. I agree with you about stubbornness being a bad quality to have.
