I will politely decline to adjust my tone for my job, for several reasons.
I talk like this when I might become emotional because it's infinitely better than yelling and screaming, and provides a possible basis for continued civil conversation. People can change, but I'm coming up from rock bottom and Rome wasn't built in a day.
I have been nothing but cordial, and have carefully selected my words. It's the content of the phrases I use, not the phrases themselves that are at fault, and the content will not change no matter how I sugarcoat it.
My job here is to be the strong arm, not to be liked. If people want to like me because of who I am when I'm not doing my job, that's fine with me, but I cannot point out people's flaws without being at least a little "mean".
Finally, anybody who gets angry enough at my criticism to quit outright probably isn't worth the effort to play with. A good RPer can adapt to any situation in or out of character. This is the internet, people get angry. Obviously because Ava is countering my points with her own points (swearing nonwithstanding), She is of the type who can not only adjust to it, but give as good as she gets instead of simply giving up. I respect her quite a bit for that.
That said.
*falls out of asshole mode*
You, Ava, are an amazing person and the only person so far (including the GM) who hasn't gotten mad at me because of my tone. I love you stay with us forever.
