When you say "dealing with [me] in person", that could mean many things, but it's sufficiently vague that it could be perceived as a threat.
I am not a homosexual. If your statement was intended to mean that you would not have difficulty in treating me as you would wish to be treated (as in "dealing with me as a person") should you ever encounter me personally (as opposed to the anonymous message-trading that goes on in this forum), I would certainly hope that that kind of behavior could be expected of you at all times and in all places, regardless of what you think you perceive of my, or anyone else's, orientation.
Just trying to make sure that I understand you.
