This Isn’t An Argument, It’s Contradiction.
…in my opinion it is respectful, intellectually honest, and strategically effective to take, as a default, an approach to others with whom we disagree that follows certain rules of thumb:
search for common ground as a starting point
do not start with the assumption that you are correct, but rather examine all points of view for logic and evidence
try to honestly understand the other side, and address the best version of the arguments and positions you are arguing against
avoid making negative assumptions about the goals, motivations, and attitudes of your opponents
when you are confident that your position in the correct (or at least superior) one, your goal should be to gently educate others, not ridicule, pontificate, showboat, or condemn.
go out of your way to acknowledge legitimate aspects or virtues of the points of view with which you generally disagree (giving the Devil his due).
freely admit your own error and make appropriate corrections. Avoid the temptation to evade, deny, or minimize your own error.
From a handy list on arguing.
