Some stereotypes are self-reinforcing. If someone tells you over and over that you are oppressed, if you hit an obstacle and fail, like all of us do at some point in our lives, a convenient excuse is that you are discriminated againstI also noticed that we are often using stuttering as an excuse for failure: I didn't get the job, girl, recognition, the promotion, the attention, the qualification BECAUSE of stuttering. But everytime I probe us, I discover that stuttering was not the cause of our failure or at least not the only one and definitely not an insurmountable one. No, we either did not have the qualification, the charm and looks, the charisma, the ability for hard and dilligent work to succeed.
Here is a story from my life. I blamed the fact that I didn't have a girlfriend on my stuttering. Then I went to a youth camp for stuttering young people organized by ELSA (European League of Stuttering Associations), and thought that now I will get a girlfriend! When that didn't work, I started thinking that maybe it was not just due to my stuttering! ;-)
So the next time you fail. don't blame it on stuttering.
