I find that he was reacting badly without much reason; you were reacting due to anger. I don't like anger but I know people usually can't contain it. When someone is in control of themselves they should always be polite. And I'm not sure if he was trying to be rude or not, but whatever.
Rants are always like that, I guess. Usually you do them at the point where you're still mad, but later you read them and feel silly. That's why they should be in blogs.
So yeah, I don't blame you, even though your rant was rude as well. ];
