Is it bad manners to slurp soup?

I did some research on whether it is bad manners or not to slurp your soup. And this is what I found.

Please note that the following answers are not mine. And not intended to be considered to be my thoughts or my feelings.

Yes, and it is horrible to be around people who do. I cant bear it when people slurp soup, isn't it better to let it cool down therefore avoiding the need to slurp?!

This is like the oldest of all the "Miss Manners" questions. Yeah, in most of the world it's considered the bad manners.

Manners at the table aren't as rigid as they used to be, but listening to slurping is straight up annoying, whether your in the dinning room or sitting in your recliner with a beer.

In the United States slurping is only a bad habit if you are with others. If you are home alone...slurp to your hearts content.

It is definitely bad manners. Worse than salting your food before getting a taste.

absolutely. Slurping is a bad habit, and bad manners. No one should be able to hear you inhale your soup.

But personally, I do find the slurping sound rather annoying. My preference is people should not slurp their soup. If it really is that hot, then wait until it cools down. If you are slurping because you have too much on your spoon, then don't put so much on. If you are slurping just to annoy someone, then you have bigger issues than slurping your soup.
