|Lose the hats, guys.|
Perhaps we can take a lesson from Cecil B. Hartley, whose A Gentleman's Guide to Etiquette was published in 1875. Yup, things don't change that much.
A few suggestions for getting along with fools, knaves and idiots:
1. Even if convinced that your opponent is utterly wrong, yield gracefully, decline further discussion, or dexterously turn the conversation, but do not obstinately defend your own opinion until you become angry…Many there are who, giving their opinion, not as an opinion but as a law, will defend their position by such phrases, as: “Well, if I were president, or governor, I would,” — and while by the warmth of their argument they prove that they are utterly unable to govern their own temper, they will endeavor to persuade you that they are perfectly competent to take charge of the government of the nation.
2. Retain, if you will, a fixed political opinion, yet do not parade it upon all occasions, and, above all, do not endeavor to force others to agree with you. Listen calmly to their ideas upon the same subjects, and if you cannot agree, differ politely, and while your opponent may set you down as a bad politician, let him be obliged to admit that you are a gentleman.
3. It is ill-bred to put on an air of weariness during a long speech from another person, and quite as rude to look at a watch, read a letter, flirt the leaves of a book, or in any other action show that you are tired of the speaker or his subject.In a dispute, if you cannot reconcile the parties, withdraw from them. You will surely make one enemy, perhaps two, by taking either side, in an argument when the speakers have lost their temper.
4. If you find you are becoming angry in a conversation, either turn to another subject or keep silence. You may utter, in the heat of passion, words which you would never use in a calmer moment, and which you would bitterly repent when they were once said.
