The greatest gift we have in a democracy is the freedom to say and think whatever we want, providing we are not also violating the rights of others.
That said, I highly doubt that calling a large portion of the electorate “retarded” is likely to help your cause. We all get that you are frustrated with the perceived short-sightedness of what-is-still their decision, but insulting them is not going to have them side with you. It certainly didn’t help Romney or Clinton, why would it help you?
If you honestly believe that this cause is worth your time enough to complain on an online forum, then it should be worth your time to go out and educate others…respectfully. That’s the greatest gift of democracy, we can share ideas and opinions and use our words to settle disagreements. If you disagree with them…it’s your right to say why.
In some ways, I agree with you, but your presentation compels others to feel shameful agreeing with you. Be part of the solution.
TLDR, don’t like something? Do something about it. I have.
