Sorry, but a little bit of brutal honesty for you. If this is how you're living your life, you are leaving a trail of people behind you that think you're an absolute dick.
The people you responded to spoke about conversations where they didn't attack their friend/partner ("you're being an arsehole"), they spoke honestly about how they felt ("Whoa, that hurt"). Both are honest, but yours is defence through attack. Their's is laying themselves bare. It's very different.
You probably like people with thick skins because they are the only people that stick around you.
...and yes, I realise I'm attacking you, but hopefully you'll take it as a friendly gesture.
