You do realize that:
1. The proposal is a ban on new assault rifles and ammo clips,
2. There are no confiscation orders in the proposed ban,
3. That the law has to pass the House and Senate to become law, and
4. The House will not pass the assault weapon ban.
Therefore, all of the wailing and gnashing of teeth is for naught. Obama gets to say "I tried" to his left wing. The right wing gets to say "we stopped him". The NRA sees an explosion of new memberships. Gun manufacturers are selling guns and ammo for 2x to 3x value to dumbasses who think Obama is going to "take my guns", and in the end, the only thing that will likely pass is the 100% background check.
Therefore, the idea of a church having a vigil to stop gun confiscation is HILARIOUS because it is stupidity on top of irony that a CHURCH is having a vigil to save a tool of violence. Like I said. Dumbasses.
