I have noticed in a great many profiles that the person lists sarcasm or a sarcastic sense of humor as if it was a major selling point. Forgive me if I'm old-fashioned, but I always believed that when someone wants to be in a relationship, it is for mutual edification, not to be raked over the coals. If I wanted that, I would attend a Don Rickles concert and sit front and center! I always equated excessive sarcasm with rudeness, but maybe today some people are turned on by it.
I admit I did communicate with a few women who listed sarcasm among their personal attributes. Both of them seemed to have enough redeeming qualities, so I decided to give them a shot. The first one was a very deep thinker capable of engaging in very intelligent conversation. When she was in a bad mood, the barbs were hurled my way with reckless abandon! One day, I decided to fire back with one of my own, and she became furious. She could dish it out, but couldn't take it. The second lady seemed far less moody. One day, she instant messaged me about a friend who treated her very badly, and she was greatly upset about it. I offered support and advice which she seemed very grateful for. Not long after, I told her of some problems I was having. Did she reciprocate the support I gave her? No! The response I got was "Too funny! lol!"
All I can say is that I am very grateful that I don't communicate with either of these snots anymore and I learned a valuable lesson about who to try to communicate with. When I see sarcasm in a profile, I keep moving along. Life is too short to put up with that.
I look forward to hearing YOUR stories of unpleasant people you may have dealt with on dating sites.

Well, for sarcasm to work, you need two things.
Someone who is clever enough to deliver it.
Someone clever enough to catch it.

I would think they would dig each other.

Sarcasm is good in moderation. I would say its a good thing that people put this on their profile so you know up front what your in for. Some people can handle it...some people consider it being an a$$hole. I personally love a sarcastic woman. I am very sarcastic and quick with a joke. If she can take it in stride and throw one right back at me, then we wil have a great time together.

Also...if a person is only sarcastic when they are mad or in a bad mood, thats not really a sarcastic trait. To me, thats a lack of respect trait. Ecspecially if you cant take what you dish out.

A good sarcastic personality has the ability to turn it on and off when needed. And know when and how far to take it. Being sarcastic to a person is a good way to see if they are uptight or not.

I find a sarcastic sense of humor to be tremendously attractive. Insensitivity is another thing entirely.

I agree that at times, a moderate amount of sarcasm can be funny, but when someone does it to be sadistic, or gets offended when the tables are turned on them, then it's a whole different matter. I am glad things didn't go any further with the second lady I mentioned. I can just imagine her reaction if I told her any bad news regarding my personal life. LOL! Too Funny! If I told her I was terminally ill and would be dead in a few days, she would say LMAO!
As for respect, it is something I highly regard, and firmly believe it to be a two-way street. Unfortunately, many people today demand it from others and refuse to reciprocate.

I have a semi-sarcastic sense of humor

it's just the way it comes out.,,I can't help it...it's part of who I am

I never intentionaly set out to hurt.... Just to make laugh

I love it on a man!!!!

Years ago, I was seeing a guy who was sarcastic/witty and we got along pretty well. That is until I was going through a very bad time and I needed to talk about it. His reply to me after I told him was "Sucks to be you" as he laughed about my situation.

I know that is said as a joke sometimes but I was on the edge of depression over what happened and that could have been the 'straw' that pushed me over that edge. Instead I yelled and cried and never looked back at that guy again.

There's definitely a right time and a wrong time for that kind of humor. The key is knowing when to use it.

Very true, Torgo.

Making fun of somebody's problems is sadistic and inexcuseable. Cracking a sarcastic joke can be funny at the right time, but doing it to rub someone else's suffering in their face shows very poor character. If the tables were turned on such people, they probably wouldn't be able to take it.

I don't think I could communicate without sarcasm...

you and about 99% of women
