Its certainly wrong.
Liberty and freedom is something we (as in, the majority of the western world) take pride in, yes ? So what would be the point of imposing such a thing on the people? Its just hypocritical.
That said, I don't really understand why people don't bother to vote... Sure if they forget or something, thats fine, but if you can, then its nothing tiresome or hard... you just go to your nearest polling station and vote for a party, whats so hard about that? (unless, of course, you live in a place where the polling station is many miles away, that I'd understand of you don't want to vote... it all depends on personal circumstances. Still, the majority of people in a democracy should be in a position where they can vote with ease.)
I think its important that we young folk do vote so that our voice is better heard. However, it must certainly be a voluntary thing.
