No, we shouldn't just tax all churches
The Alliance Defending Freedom and others have been hard at work for years organizing pastors to challenge (i.e., break) tax laws by electioneering from the pulpit. ADF insists this is about a pastor’s freedom of expression. I’m inclined to land where Amelia Thomson-Deveaux does: You can say anything you want (legally; let’s save theological arguments for another time)—once you give up your tax-exempt status.
But Matthew Yglesias takes this a step farther:
Let's tax churches! All of them, in a non-discriminatory way that doesn't consider faith or creed or level of political engagement.
