You appear to be putting far too much emphasis on the 'ignorance is bliss' idea.
This is more complex than you want to think; Your narrow focus that assumes (incorrectly) that freedom on small scale questions implies greater freedom on a larger scale is deeply flawed, but you would rather stick to your ideology than consider any possibility that it might be in error.
Freedom from participation in democracy is no less dangerous to freedom for an entire polity than are any other limitations on the franchise.
Too much democracy is bad; But fake democracy (in which only the enthusiasts and extremists have a voice) is even worse. Of course you disagree with both of these claims - but I implore you not to let that stop you from thinking about whether they might not nevertheless be true.
As H L Mencken said, "For every complex problem there is an answer that is clear, simple, and wrong".
You babbled a lot and did not address my actual point.
My point is involving apathetic, disinterested, uneducated people in decision making likely makes decision making worse.
Many of us experience this in our daily lives. We don't force lazy uninformed people to vote on how our brain surgeries ought to be done, or how our taxes ought to be filed, our on what we have for dinner tonight.
Generally the more important the decision is to me, the less I want to point guns at lazy uninformed people and force them to make it for me.
Now, If you want to argue elections are so stupidly trivial we want to force the lazy and apathetic to participate in them you'd be on more solid ground, but you still don't have a good reason for "why?"
If elections are trivial and unimportant why use force to make people participate in them?
