To me, this type of speech seems out of place for such "discussions":

X says: "C'mon Y, I have explained this point to you over and over for months and you refuse to listen to me!!!"

This is insulting of Y, not uplifting or exhorting or even correcting. And it is arrogant of X, who misses the possibility that arguments that are convincing to himself are not [yet] convincing to others.

This stuff comes across to me as pure impatience, among other things, and it goes both directions (credo/paedo). Gently correct those who are in opposition. Be patient when wronged. Deal gently with the ignorant and misguided <Heb 5:2> (whomever you identify them to be).

My two cents... :-)
