There is one key to the Schumer-backed DISCLOSE Act that makes it dangerous for gun owners who want to organize in any meaningful manner: disclosure of all donors/members whose money may have funded independent expenditures to the FEC.
According to The New York Times, a “reform” bill might require advocacy groups (such as NRA) “to identify all their financial donors or set up separate accounts to handle political spending and identify the donors to that account.”The FEC donor databases are open to all, and the most user-friendly that makes looking up individuals easy and fast is the database available at OpenSecrets.org. Kopel uses the example that your boss could decide to cross-reference you to find out what you’re up to outside of work hours. At that point, you just have to hope he/she isn’t anti-gun, or you may find yourself in the unemployment line. Even if NRA maintains a separate fund for campaign expenditures, you can’t donate if you value your privacy.
Simply put: If NRA wants to use its general funds from member dues to speak out during election season, then NRA would have to give the federal government a list of every single NRA member.
The bastard and his friends just can't stand it that people have the right to oppose them without paying a penalty, so they want to create at least the threat of penalty to try to shut people up.
