It seems the goal is to actually GET the IRS to take someone to court because once that happens, then a suit can be filed to challenge the Johnson amendment. The claim is that the IRS uses the amendment as a fear tactic to silence churches, but that they won't ever prosecute anyone because if they do, they know the Johnson amendment itself will get challenged and overturned.
Here's another look at the movement:
Very interested to see where this goes. Supposedly a bunch of pastors participated in 2011, sent their videos and sermons to the IRS...and none of them were prosecuted.
