It's this mentality that stops people from approaching a hobby or craft. The idea that there's just "one correct way" to do it, and that's it. Like you can't drink beer ice cold, and the only beer is beer that comes in brown glass. You can't drink whisky with coke, or on ice, it should be with a drop of water (spring water) only, and in a Glencairn glass. You can't braai steak until well done, you can't go camping with a satellite dish or a TV, etc. etc.
Coffee is the same, FYI, and an espresso or filter or pour-over and whatever isn't the "proper way to consume coffee" either. The proper way to cup coffee is literally just ground coffee into a cup, with hot water on top. I'm 99.9% sure that nobody here does that as their daily morning wake-up brew either.
