It's not tone, it's absence of content. Once you need to make it about me, it means you've given up on discussing what I said. What's true is true no matter who says it, even if you were right about everything you said it wouldn't change a single thing.
Though if you could be polite too that'd be stellar. Manners and consideration are not weakness.
You stopped discussing things several posts ago, I noticed. I told you that you did so. Why are you repeating to me what I said to you over my last 2 replies as if it's news?! I've been snarkily complaining about it. It's not news!
