The way I see it, you overreacted, got called on it by someone and then apologised. I'm sure Koop is over it and accepted the apology, so it seems like case closed to me. However, to suggest that you need to play in the ABBL to express an opinion here is ridiculous. If you post on a public forum for anyone to see, you must accept that anyone has a right to reply and express their opinion.
My comments weren't abusive, they were an opinion. Telling someone that posting a rant after being CT'd makes them seem like a sore loser is not 'abuse'.
