There are instances where people need to produce proof through a valid ID as part of their everyday lives, it's not as if the we are reaching towards a concept that is so completely foreign to many of us. Whether it's a library card, air travel, or even purchasing alcohol, a valid ID has never been proven to be a hindrance throughout our society's day to day lifestyle.
The shackles of big government are imposed on us via incremental encroachments that are always pitched as "minor inconveniences". We should resist such encroachment, especially when motivated by duplicitous politics.
The only problem with your theory? The left is cheating in order to take the very rights you claim to hold so dear.
And showing an ID to vote is the least of our problems when it comes to the erosion of our freedoms.
They're "cheating" with bread and circuses, and by media manipulation. And while there very well may be election fraud going on, it's ridiculously implausible to suggest it's happening at the individual voter level. There are far more effective ways to steal elections, ways that voter id laws will never touch.
This issue just doesn't pass the bullshit test for me. It's a purely partisan attempt to squelch "undesirable" votes.
