Tell that to my asshole. I’ve tried training it to be silent on the shitter for near 40 years but it fails more often than not.

I had a friend growing up who ate with his mouth open. I fucking hated it. But he had problems breathing through his nose due to something with his soft tissue in his throat. So, you learn to ignore it.

Actually what’s virtuous is just having a fucking door on the bathroom

I agree but only because that's the standard for our culture so somebody not doing it is probably being disrespectful which means it becomes offensive to others because it normally only comes from people with some sort of negative feeling or inconsiderateness for those around them. In some cultures, noisy eating is the proper way and shows you're enjoying the food. Same goes for clothes, toilet sounds, etc. It's a lot more repulsive seeing a human poo on the street than a dog even though it's not fundamentally very different.

> even though it's not fundamentally very different.

There's a pretty significant difference; human diseases are much more likely to spread to other humans.

> Same goes for clothes, toilet sounds, etc.

What do you mean "same goes"? Are you saying there are cultures in which being loud on the toilet is considered proper?

No it isn't. You can slurp noodles without being rude but they do not consider 'loud mouth noises' respectful.

First link: That is a Swedish robotics blog and the sources linked are just landing pages for Chinese tours or language lessons.

Second link: Where do they say that 'making loud mouth noises is a sign of respect'? They say 'people slurp noodles' which is exactly what I said.

> It's so common that the only logical explanation is that it is encouraged. It appears to be the norm and the non-slurper is the exception. I'm glad that your parents taught you to not slurp. You are an exceptional individual.

Anyway I’ve asked enough Chinese people about it to get the same answer. Not all do it, but some do it for these reasons.

I doubt you ever asked any Chinese.

They are saying it is normal to slurp noodles, which is what I said in my first reply to you. They did not say that they make 'loud mouth noises' as a sign of respect.

Ask this specific question: "Do you make loud mouth noises while you eat as a sign of respect, or is it just normal to slurp noodles?" and see what answer you get.
