To my conservative friends out there who are in favor of campaign disclosure laws, Mozilla should be a warning. The entire purpose of these laws is to intimidate opponents. Make no mistake about it, the only reason that liberals want to name campaign donors is so they can harass and take revenge upon their political enemies.
Ask yourself why elections are held by secret ballot. Because if they were held in public, each individual would be subject to enormous pressure by whoever happens to be the biggest bully. Think about it from the perspective of the bully. If you don't know who voted against you, you don't know who to take retribution on.
In essence, campaign finance disclosure laws take away the secret ballot. If you know who I donated money to, you pretty much know who I'm going to vote for. It paints a big target for every bully out there and it's wrong.
Don't be foolish and think any of this is about "transparency", it's about coercion, plain and simple.
