I am Catholic and it annoys me to no end when priests do this as if a politician is even honest about what they claim to support half the time in the first place. I didn't know I could report them! Where's the form?!
I was just about to post this haha, (I think this is the actual form you have to fill out tho)
To anyone saying the IRS would never enforce this, be the change you want to see in the world. Continue reporting until they start to enforce it. Even if they don't, better to keep trying than living with a defeatist attitude.
Most priests I have met just consider it a job, not so much a reflection of their own holiness. Some of them are true shepherds, but a lot of them are sheep themselves. A few are wolves, unworthy of the office at all. Going to seminary opened up my eyes to a lot of things behind the scenes that are both inspiring and unsavory. The best kinds of priests I have found are usually the ones running retreats. I think the Bishops know and try to get them to be a good influence on people SENT to retreats... Anyway, do not confuse the faith for the shoddy work of a few old guys who answer to more old guys. Remember, Jesus Himself picked Judas and look what he did.
