And, you do a very good job!  

Thank you! I very much appreciate a kind word.

You might want to be more explicit in your profile declaration so as to minimize confusion going forward.

I probably should...

But I dislike the idea that we are playing team sports, where we put on the colors, root for our own side and hate on the others. 

But you're right, "Um..." as a descriptor may be a bit too obscure.
