I actually do consider that, but we live in the reality of how it works and not how we wish it would. In the US, the voting system is the majority that shows up. I recognize we basically never get a true majority of those registered to vote much less of people in general.

It would be far more meaningful if those who actually wanted to protest turned in blank ballots. At best non voting is an ignored abstention at at worst simply recognized as not caring enough to even have a voice in the process.

People who do not vote are absolutely not "casting a vote against democracy". They lack of participation doesn't damage it one iota. Making a statement involved action. Not non participation and acceptance.
