Completely believable. This is their main tactic and it works very, very, well.
And you pay for the ACLU with your tax dollars to take your tax dollars.
The only reason the tactic works is the ‘private attorney general’ provision of the Civil Rights Act. Efforts to eliminate that provision are regularly shot down in Congress. A similar provision in California law permitted shakedowns of thousands of businesses until the citizens finally repealed the act by referendum. Sadly, there’s no similar means for the citizens to directly deal with the consequences of so-called representative federal legislators who fail to represent the citizens.
