You’re helping me with the goal you assume I have.

It’s condescending because instead of inferring my communication goals from my message, you assume the message is poorly crafted because it doesn’t effectively reach that goal.

I was hoping to lead you do this realization indirectly, but I’ll just come out and say it: my goal with that comment was to express my feelings. Do you feel that you know how I feel about this topic, having read my comment?

That’s why I asked whether you understand what tone is. You seem to think tone is a lubricant that makes manipulating others’ opinions go easier. I disagree. I think tone is an expression of emotion.

Ask yourself honestly. Did you get a good sense of how I feel about this, from reading my comment? If you did, then I succeeded in my communications goal.

Since we’re doing unsolicited advice, I’d say take it easy on the assumptions of others’ incompetence when you’re encountering them for the first time.
