TO the very original question. To see the answer you have to know what in fact manners are. Manners are a set of actions/customs set up by HUMANS . So you must also ask were manners ever important? EVER? you cannot make a conclusion . manners made by humans closeley resemble a set of morals originally set by god, which do infact matter .
SO manners are various persons personal preffrences on how to output gods morals with their output. Times change and people change. That voids any possibility of it mattering if manners matter . So the answer to your question is as always right at home with god. What matters isnt the manners, but the morals.
U notice how people in other countries deal with their kids mannerwise. They are much more strict, much more to the point than the timeout and ground you parents in america. Do you think they ever ask if manners are important anymore. no they will just beat the child senseless or something. THey love that kid and theres no blanket of deception hitting them. Whats hitting them is the claw of famine most likely. Since they have no money. But they never ask if manners matter. THey see into things we cant see into. We see into things they cant see into. With our wealth and luxuries we lose some happiness and we lose touch of our morals. With their low budget lives they are still given more happiness and have stronger touch of their morals. Everythings a big circle what goes up comes down and all this is stated in the bible, these concepts are described metephorically and have held true for all of existence so far and yet people are still blind. People here in america particularly . we are blinded with the luxuries. We are blinded with the luxuries. We are blinded with the luxuries. IF you know your blinded by the bright light of your luxuries put on your sun glasses so you know from the shade of your glasses that its just light blinding you. And with your sun glasses blocking the glare you can see the reality around you still, it will be a darkenned reality shaded with question and uncertainty, but with your sunglasses you can manage. Sun glasses come at a price tho. The price being this. Give up the temptation. A price is a take away from what there is. IN your pocket or in your world. Giveup temptation, Dont get lost , dont believe what you see without question from your own mind. This is called thinking for yourself. And now that this nation thinks with MTV and money and cars and ho's ... So many people are running around without sunglasses. This is why the country is as flawed as i say it is. This is the bottom line. If anyone is to say something else is the bottom line it is either going to be god satan or wrong. And if its wrong it will be a bottom line you made and messed up because the sunglasses arent on you. Put them on.
