Is it normal to be a gentleman?

It's implied when told to be a gentleman, as in my book (shipped from the USA) '50 Things Every Young Gentleman Should Know' which is for 14 year old teenagers and young adults from 18 to 35, that you should only follow gentlemanly rules and no other rules, the real truth is it's not gentlemanly to go to any pub because it's too unfriendly for any gentleman to handle and because a gentleman should know better than to spend time in places that have rules and therefore interfere with his niceness. The pubs are anti-nice policies and way too pessimistic for a gentleman, that's what's implied subtly in my book when it mentions restaurants and ignores rough places like pubs, it's saying that a gentleman only gets taken to nice places, like my parents taking me to a fancy restaurant on my 35th birthday. That was nearly a year ago (I'm still 35) and gentlemen can't handle a single fart, controls it, and is so chivalrous as to never interact with a farting person. That's how it works, he only spends time with his chivalrous, polite and courteous friends. Therefore I was thinking of following only one set of rules for the first time and I have been a gentleman for many many years since my schoolmates and all the posh people told me I was very polite. That's the confidence back then whereas people are selfish and don't want me to push them in their seats towards the table, without shoving, which is a gentlemanly thing to do. And as a dandy gentleman I almost always wear a tie which is what people should do in every restaurant. It's probably necessary for a gentleman to dress up in a stripy undershirt, a suit and slacks when entering a strip club not because it has a dress code but because the clothes are agreeable everywhere you go. But a gentleman never goes there with his parents. The above etiquette book implies that when you grow into a man you're no longer cute, and that you have to act cute and take responsibility, act like a man, and that you can't do whatever you want, there's a lot of things you have to do to impress your wife, your girlfriend and to impress your parents. Gentlemen don't give gestures like offering an unwanted food nor do they force their gentlemanliness on others, as I soon found out, gentlemen are refined, posh, and that implies that they're saints compared to you, no offence. So long and not long ago I decided to help a man in a wheelchair giving him the same courtesies as I would to anyone else, ignoring that scratch on his arm (which is politically correct), and also I never reminded anyone of their past mistakes, also doors are open with my parents who want to give me privileges, especially my mother, and I never burp (not on purpose), I eat whenever possible all my food, I don't scrape it in the bin, I put on the tie whenever I head to the city, and I shake hands firmly and introduce the younger person to the older person and never the older person to the younger person, I never talk in theatres, I listen paying attention straight away after busy when talked to, even if it's abrupt and rude to talk to me whilst I'm busy, otherwise I tell them "please shut up!", as a gentleman I say excuse me and never wait 15 minutes for someone to stop talking, but I stamp my foot on the ground until I'm excused straight away, and saying "you're excused" is more pleasant and better manners than saying "you are not excused!" which is rude. Also I hate being kept waiting, having patience, and keeping people waiting is bad manners not only because it's bad manners but because it upsets and inconveniences people and that they lose their patience (I'll call the Onbudsman for that), therefore I never keep people waiting. People are acting selfish, and it's wrong, as I recently realized, to be selfish even if we're all selfish, there's no justification for it. Gentlemanliness is selfless, it's never selfish, and is good in every way and when I thought it was the same thing as being good I was right, but it's not the same thing as morals and ethics, which focusses on the good and bad, gentlemanliness focusses only on the good, is that normal?
