why writing all in capital in consider RUDE?

Writing in capitals is considered to be shouting, AND it can be hard to read.  \nCapitalize words only to highlight an important point or to distinguish a title or heading.

You shouldn't be nice to Americans, they're mostly stupid rude and lazy. Clever insults are more fun to read anyway. PS I'm American.

If you are using Internet Explorer, go to View, Text Size and left click on Larger or Largest.\nIn Internet etiquette, using all capital letters is considered shouting.

Well, we Americans are often criticized for being lazy. To make a capital letter, you need to press the "shift" key. Since most people like to get things done the quickest, easiest way, they don't want to spend that extra millisecond (sp?) pressing that key. Hey, we're living in fast paced society! Just a guess. P.S. It drives me nuts when people do stuff like that too!

I doesn't make me angry, but it is a general understanding that it means that you are angry.\n\nAlso, if I see a long post that is all caps, I just skip it, because it is annoying to read.  Don't know why, just is.

Rude as hell. \nAny noise that is loud enough to disturb is a pollutant. Plus this behavior smacks of total disregard of other peoples comfort and should be fined/banned/beheaded (kidding :P)!

Caps are used to stress something.  In most cases, it's considered shouting.  Ex: WHY AREN'T YOU LISTENING TO ME!!!

I don't know. Maybe that's because they think people should be able to understand them. Personally, I only shorten laughing out loud, you know, lol, or curses "WTF?" If I'm responding to someone who contacts me, I shorten because to b/c, with to w/, an without to w/out because there are only so many characters you can use. These type of abbreviations are okay on question since there is also a limit of characters. However, I think there are some people who just don't realize there's a "check spelling" right there. It's amazing to see how many totally illiterate people there are out there.

WRITING IN CAP SHOWS YOU ARE RAISING YOUR VOICE OR YELLING if you use regular font, it shows you are shoing you are calm, or not yelling...

A boldface lie: "Hi, I'm here from the government, and I'd like to help". We type your names in all capital letters when we mail you anything, because in Business Law this denotes a corporation not a living being.  The body of the letter to you is in capital and lower case letters. Everything the government does is legal, and done from a legal perspective. We are NOT yelling at you when we address you, merely being legal. You are a dead entity; a fiction, you only exist on paper or as an entry in a computer bank. It has nothing to do with Etiquette or yelling or any such nonsense as that.  All caps denotes you, as far as we are concerned.\n\nOne more thing that may seem confusing to you, from a legal perspective.... Your address is not really the house number on the building you reside at. That information actually belongs to the Post Office, not to you. It is therefore their address, not yours. \n\nTechnically, as well as legally, you are addressed by your Christian name and your given name. To be legal and in good standing they should always be written out in capital letters and lower case letters in order to represent a living being. This also means no abreviations for your middle name, if you were given one. Example:  John Q. Public should be written out as John Quincy, Public with a comma or semi-colon separating the given name from the family names....to be legal.  Bottom line: your name is your address, not some numbers on a building.\n\nOther uses on this site and others like it use the all caps because of the lack of emphasis available to the writer in this format. No color, font sizing, no underlining, no bold facing, etc.  Hope this helps.

Because they're totally hypocritical bar-stewards, that's why!!\n\nTHAT is why 2 of your previous repliers have chosen to insult your spelling, instead of answering your question! Personally, I feel that although your spelling may not be great it's still a lot better than the spelling of SOME native English speakers ... but THEY are American too!\n; )\n\nAt least your writing can be understood, and I agree with you 100%!\n(But then, I'm not American, so I'm not insulted!)

Yahoo! Answers doesn't allow you to use all caps in questions because they want to keep the format standardized. When going through a list of questions, it's easier to read them all if they use regular capitalization. The extra space provided by the lower case levels makes it easier for me to read and for many other people.\n\nSingle questions with all caps are considered shouting, as explained above. This does draw extra attention to particular questions, but in doing so it draws attention away from others which may get overlooked.

Could be that the Caps Lock is on.
