My main point was just that something being legal doesn't make it useless in the quest for human freedom.
There is no relation to something being legal and how useful it is in the quest for human freedom. So, yes, I agree with you. I am not sure that voting is even designed as a tool to increase human freedom. It is a true, but is often used to decrease human freedom.
Absolutely. Voting is more often used to decrease my freedom. But it can be used to increase it.
You bet! I don't vote for people, but I do vote down every initiative and referendum that makes the government larger, more debt driven, and more intrusive. Occasionally, I vote for one that reverses that process (usually constitutional amendments forbidding the legislature to make certain types of laws.)
