Okay, allow me to jump in.

You both maybe want to take it down a notch, or move somewhere more private, like PM, maybe? I didn't try to side anyone, my main concern here is a fact that if a future renter wanted to rent a space on your office, one of the possible things they will do is checking this thread. If you put yourself on his position, what do you think the impression he'll get? Definitely an investor throwing words with the represtative that's gradually became more and more less schooled is not on their top list, and will definitely not a major selling point.

I snipped the entire conversation, so please, edit your sentences.
