Your "right to complain" and participate as part of civil society is most certainly not handed out as a prize for voting. There are more meaningful ways that you can contribute to the world than by sticking a piece of paper in a cardboard box once every few years.
If you want to vote, vote well. If you don't think you can vote well with the time you have available today, it's ok! There are a lot of ways that you can make the world a better place. Today isn't your only chance.
How to vote well:
If you're going to vote, you should do it responsibly. Reading the platforms written by the advertisers for each party is not informing yourself. You should, at a minimum, have read some basic economics. Understood the trade-offs that each policy stand that you take are likely to have, and decided that those trade-offs *are worth it* - not that they don't matter or don't exist. You should try to identify your own cognitive biases and do your best to overcome them before making a decision. You need to be comfortable with the idea that any policy that you're approving for your own benefit can be used by someone you disagree with in the future.
The idea that everybody ought to vote comes from the idea that so long as enough of us vote, we cancel out each others' mistakes and come up with the best solution. But if voters don't overcome their policy misconceptions, the more people vote, the more wrong the outcome will be.
