Why do people leave sarcastic respostas on most questions?

that's because it is the response to stupidity...

They want Best Answer.

Because they want to be funny and get voted best answer, and people like a good laugh, so there's no harm, really.

Why not?

Sarcasm is a natural bodies defense against their stupidity.

I do, because I have a MAJOR sarcastic sense of humor, and you can blame that on my 5th grade teacher. Other people, no idea.

That's because we feel like it. Can't handle it? Don't read the answers.

My mind works like that. Don't like? Don't read.
Not everyone is sarcastic, I'm not (All the time)
Why does it even bug you? Its actually funny if your smart enough to get it.

Because they feel like it.

They can. Therefore, they will. And have you seen half the perguntas posted on this spot? They aren't very smart to begin with. So in my opinion, "Sarcasm is a response to stupidity" is perfectly justified.

I agree, sarcasm is natural, but people over here its like they are paid for being VERY sarcastic. Anyways we cant help it.

Because it's funny. I use sarcasm on most of my respostas but not all. Some of them involve personal situations and people's feelings which can easily get hurt so I stay away from sarcasm when it comes to those kind of questions. I agree, sometimes when people take the pergunta too literally and answer it sarcastically it drives me a little crazy. I see enough of it.

I don't know why they do that because I never do, I always mean what I say in my comments and answers!

It depends of the questions.
A serious pergunta = A serious answer
A highly stupid pergunta = An answer full of sarcasm.
^ Most perguntas on here are like that.

*Insert sarcastic comment here.*

it's my opinion
because in real life i think they are really miss attention from people ,they wanna get best answer to be honest ,i wanted to,but now i give up ,they misunderstand themselves and the world!!!!

OK. Well, firstly, everybody is different.

I mean, you may not find sarcasm funny, but for a lot of people, that is their sense of humour.
For example, you may prefer "knock knock" jokes but personally, I don't find them funny at all, never have, never will but I prefer sarcastic jokes or atuação out stupid impressions.

Secondly, when they see a pergunta on "Random" what else would they post. I mean the name of the site/spot doesn't exactly entitle a serious response to whatever is posted on here, there are other spots for that kind of thing. But if you're going to post a serious pergunta or whatever, just say something like, "please, no jokes or sarcasm, I'm totally serious, I really need help, blah, blah blah". I've done it a few times and people have respected that.

I think you should respect what others find funny but if you cannot take the sarcasm, or if you don't like it, then don't read the answer or just ignore it, I mean it's not like you'll ever see or meet these people anyway, right? So, I understand why it bothers you, but you just need to learn to ignore it.

Sarcasm is my response to stupidity shit.

Because sarcasm is fun.

lookin for attenrion and fãs i guess

Because some people are naturally sarcastic.

*sarcastically* oh really? i havent seen any sarcasm.

coz its "funny"...jus to make the situation light.........but mostly it turns out the opposite is happening

It makes them look smart
