8. Politics.
If your critic is from a different “political” party, their criticism may be rooted in opinion, not fact. Mark Twain once said, “We all know that in all matters of mere opinion that man is insane. Democrats are insane to Republicans and Republicans are insane to Democrats. The rule is perfect: in all matters of opinion our adversaries are insane.” Recognize that some criticism will come your way because of your “party”, not you personally.
