Some of these are very silly. There's nothing wrong with golf umbrellas unless you're in a crowded place; pointing is fine, so long as you're not pointing at something with feelings; the advice on accepting compliments doesn't mention why you should accept and move on (it's because deflecting makes the other person compliment you even more, which is narcissistic); at least half my female friends laugh at or are offended by faux-gallantry like going through a door first, even though they appreciate actually important things like waiting with them until their ride home arrives; urinal etiquette is contextual, and at a music festival after 12am it's probably rude not to talk; ordering everything medium-rare fails to take into account the unique qualities of the cut of meat; you can eat oysters however you want, and there's nothing wrong with mingonette nor other vinegar-based garnishes; and so on for all the rest.
