because everyone still nag about it anyway, well now if they didn't vote they wouldn't have had the right nag now they do.
most ppl care about politics in belgium. not a great deal but they know what the political parties stand for so they know what they will get if they vote for one.
the most important reason is to make sure that the less fortunate: the homeless, the poor, the ppl who live on the edge of society aren't forgotten.
Because I and almost everyone from the socialist party (of which I am a member) believes that those groups on the edge of society will be forgotten once they aren't forced to come and vote anymore. why would politicians take into account ppl who wont come to vote for them anywayz.
as a personal reason: ppl died to give everyone the right to vote out of pure and utter respect we should all go and vote.
