When did they make it compulsory?
1924 according to Wikipedia, well before I was born at least. Seems to nor be a big issue for us.
So it's preferable to put them in a booth so they can blindly mark the paper and just get it over with?
Votes should mean something. It's fairly obvious that when you force someone to vote (by telling them they will be penalized if they don't), they are doing so begrudgingly.
First of all technically they're not put in a voting booth, they are standing at a desk and the decision to bother with the booth (and fill in the form correctly) is up to them.
And my impression of the system is that vast vast majority of people while maybe being a tad apathetic about politics in general and may have a little whine about it actually have an opinion they'd like to have heard. That's why our system has stayed the way it has, every now and again the idea of stopping it comes up but it never gets much traction with people.
Yes there are people who literally don't care at all who also have to show up but numbers aren't as bad as you assume I think and they probably make up the majority of the donkey votes/informal votes.
So, participation is so essential that you think bulldozing the freedom to not participate is required? This is strictly a matter of liberty and I guess that is my ideology...thankfully that is the way the framers of this country saw it also.
How is this a bulldozing of freedom? Oh my you need to spend less than an hour every few years getting your name ticked off a list! What is this North Korea? (That was sarcasm)
Seriously you probably spend more time doing your taxes, let alone the percentage of time you spend working to pay those taxes (+/- someone to fill them for you instead). And if you oppose all those things in their entirety then you are an anarchist.
Given that most people in this country take no active part in the way government works to begin with, I am glad they choose not to give their uninformed opinion at the ballot box.
The problem is that it then becomes a contest of who can encourage their pre-existing support base to be the least apathetic. There is no guarantee those people (from all political persuasions) are any better informed than others, in some cases their motivation might spring from how profoundly misinformed they are.
Then you will also have many people (generally centrists/moderates) with well thought out opinions who stay away because they know they'll be drowned out by frenzied idealogues from both sides (a self fulfilling prophecy as if all such people voted they wouldn't be drowned out).
