That doesn't make sense. You would vote and be politically active to what you want to happen. If this view was a broad-consensus, then the system would change. If you want to make politicians more accountable, vote for those who hold accountability dear, and campaign for it.
Not voting would be the same as accepting a 5-years-olds scribble going "it is the best it is going to be, no point in trying", opposed to tearing it up, appealing to those with artistic skills and merits and trying to change it to something actually good.
So your 'strong interest in democracy' is an oxymoron since the actions you pursue entail attempting to destroy democracy. Whilst there is far more to it than simply 'voting', not voting is like not bothering to use toilet-paper and not even washing your hands afterwards, then going off complaining how your sandwich tastes disgusting.
