Sure it was you:

… the regulations focus on the word “substantial” which has never been decided.
So perhaps it is time to find out what it means exactly in this context.

My claim is that I am fine if the IRS look into its regulations on the matter. That is all.
And if that had truly been your claim, you’d hear not a peep from me.
If that is now the only claim you wish to defend… that’s fine. I, too, would not object if the IRS were to “look into” the matter. If the IRS were to suggest to Congress that the regulations be changed, then I might be fine with it, or I might be virulently opposed, depending on the nature of the proposed changes.
Should they do so, I don’t doubt that both there will be court fights on the matter, and that the Mormons will (quite likely properly) skate on past transgressions because the new regulations will not be applied retroactively.
Yes, although I’ll just point out that what is at issue here is not simply an administrative regulation created and enforced by the IRS, but the law of the United States, made by the Congress: 26 U.S.C. § 4911 et seq. But for that nitpick between “regulation” and “law,” I agree.
In the future, before you deem yourself my spokesman, able to say for me what I have said in the past, please review your correspondence from me to see if there is any such authorization. I assure SDMB members there is not, nor will there ever be.
I don’t need your authorization to read, refer to, and report your prior posts, much as you wish to pretend they don’t say what they plainly do:

… the regulations focus on the word “substantial” which has never been decided.
So perhaps it is time to find out what it means exactly in this context.

…so, just to remind you in case you forgot from a few paragraphs ago, I don’t know if LDS church has violated IRS regulations, and neither do you. As we discussed, courts exist to settle disputes. If there is a dispute, then Courts will decide.
Yeah, actually, I do. Because I can read.
Your statement is like saying, “I don’t know if President Obama was born in Kenya, and neither do you. As we discussed, courts exist to settle disputes. If there is a dispute, then Courts will decide. No court has decided the issue of President Obama’s birth. Thus, we just don’t know.”
But we do, even though no court has decided the issue. Because, you see, we can read his birth announcement in Hawaii papers, the copy of his birth certificate that’s been published, and form our own conclusion. I can even acknowledge that a mathematically-non-zero chance exists that he will turn out to have been born in Kenya and still say we know he wasn’t.
So, precisely, with this issue. You can’t retreat into saying that because no court has considered the issue, we don’t know… because a court HAS considered another case where expenditures were less than 5% and concluded that when expenditures are less than 5%, that’s not substantial. There may be a mathematically non-zero chance that this will change, but it’s on the close order of Obama’s Kenyan birth chances.
It doesn’t take a rocket scientist to know that I have suggested that the regulations themselves are what need to be reconsidered in light of the recent church tactics.
Again, if your contribution here had been to say, “Why, that’s outrageous! The kind of participation by the Mormon church should be prevented by a non-profit, and the law needs to change to reflect this!” then my comment would have been: nothing.
But you didn’t say that. No, no. You said:

… the regulations focus on the word “substantial” which has never been decided.
So perhaps it is time to find out what it means exactly in this context.
That’s not “let’s change the law.” That’s “Let’s see if the law applies to what they did.” And having been informed that it does not, your reaction should have been, “Oh. OK. I did not know that. Why, that’s outrageous! The kind of participation by the Mormon church should be prevented by a non-profit, and the law needs to change to reflect this!”
At which point my reply would have been: silence. Because that makes perfect sense.
Own up to your quote, not alice, because it’s right there where everyone can see it.
