I replied to state my disagreement and end my participation to the conversation politely, nothing more.

To which you replied (but edited later):

    Okay thanks for pointing out exactly how I typed my 
    paragraph. Did you offer any sort of rebuttal? No. Stop 
    being a baby.

This is obviously going nowhere - so yes I'm leaving the discussion.

I'm now back to my regular schedule, arms uncrossed (I rarely cross them, mind you), actually. Have a nice end of day (sincerely).
