In America, Your symbol would be an (I), for irrelevant. Being an independent is like abstaining from the political process. It's "independents" (typically moderates) that by their silence allow extremists to take over political parties for their own evil devices.
I am an Independent, and I'm far from silent or irrelevant.
I use to be a Republican (long before many of you were born) but switched to an Independent until the Reform movement of Perot came along. While I disagreed with some of his views, he addressed many of my concerns, such as "business as usual" needed to stop between the two dominant parties. I have long believed that our society cannot be cookie-cuttered into either Party A or Party B. As we clearly see, each party contains their own "sub Party" which focus on key points which are in conflict with the main party's core ideals. After Perot came and went, I've carried on the soul of the movement for reform, and have carried it to the ending of the domination by the democrat and republican parties. Time to get true representation of the population in government, and that can only occur when there are more choices for the voting population to choose from.
