And I do not see what is aggressive about my response. This really gets me on this side, people who say things freely feel attacked when someone tells them they were wrong. I certainly did not try to attack anyone, I felt like defending the one who was right. I would even apologize had I known for what. Peace people!
I certainly don't think you're an aggressive person. However sentence like "And perhaps speak less hastily of things others know more about" sounds a bit snotty. I'm sure you didn't mean it that way, but if someone said that thing to me I'd not be amused.
