Only problem with the idea of forced voting is that many citizens of all countries are not well-informed. Simply put everyone doesn't have the resources to vote. I'm not just talking about getting to the poll, but also being able to be fully aware of each side's positions and their implications. Thus such egalitarian ideas are futile, but hopefully one day they will not be. And that time may come soon enough with the advances in technology. Therefore as of now forcing everyone to vote would simply be to the detriment of a country.
Moreover Plato points out that democracy is essentially governed by those who are popular not those who are best suited for the job. Just look around you today and you'll see the results of democracy. It incentives short-term policies at the expense of a country's future. Even if everyone can afford to vote by missing work and staying well-informed it wouldn't do much good. It would simply be a bigger election for class president determined by arbitrary factors that are irrelevant to the nation.
In conclusion, yes, you are wise and correct for being against such an unpragmatic policy. There are no real tangible advantages to forcing citizens to vote, but there are MANY costly disadvantages.
Maybe the right question to ask is why was this particular policy enacted and what is their agenda?
