If you’re trying to compare TF2 to Overwatch or Overwatch to TF2 and NOT expecting any arguments to form, maybe you shouldn’t start off your post’s title in giant bold letters that say “TF2 is better than Overwatch” or “Overwatch is better than TF2” before stating all your opinions on them both
Starting off like that will usually give the impression that you’re challenging the reader to fight you if they think different, and some will do so out of defense.
I have no idea what makes you think that won’t start something. Unless you’re doing it on purpose, which is a total dick move.
