That's a fallacious argument, as there exists no such feat.
Yes, it does. He just created it. If he slapped the d20 logo and legal stuff on it, he could sell this feat.
It's not "official" (meaning "made by Wizards"), but it does exist.
I am the first to admit that WOTC's grasp of balance is at times shaky, but your example is so extreme as to constitute parody.
I think that was his intention: To create an extreme example.
However, name any legally valid "broken" build. I am almost certain that, as a DM, I would find ways to challenge that build within the limitations of EL - not once, but repeatedly.
Sure, the DM should always be able to challenge whatever build there is. But the DM could give nukes to kobolds. What counts is how far out of the way the DM would have to go - both to challenge the build and not to obliterate the rest of the party - which consists of sensible characters.

That's not exactly what I'm saying. It's perfectly within the DM's purview to approve or disprove individual PrCs, for example, and that would make a clear example wherein a DM approves part of a book but does not approve another part of it. However, fundamentally, you must consider that what you are doing is saying that it is OK for one person to get a power increase, but not for another person to get a power increase from the very same source.
Yes, he is saying that. So am I. The reason is simple: Just because they're from the same source doesn't mean that they're equally valid. Often, there's perfectly good stuff in a book that contains a really broken rule tidbit. Then that broken rule has to be taken down, but that doesn't mean the rest of the book must be beyond limits, either.
And he's not picking on the playe who wanted that broken rule. Said player can choose any other stuff from the book the DM approves off. He could get the very same feat/spell/whatever that other player took. And said other player couldn't get the broken rulepiece, either. Noone's saying "this rule is banned - for you!". In fact, shame on the player for choosing broken rules and throwing a fit when he may not use it. That was one of the main reasons I threw a player out of my group.
I think it would be perfectly natural to see that as injustice, and IME players tend to assume injustice is the result of favoritism (or outright cluelessness, but I doubt you would be accused of that.)
Yes, but it isn't favouritism, so there's no injustice. If the player won't see that his choice is broken, but the other made a more sensible choice, then that player is clueless. Throwing a tantrum right after makes him clueless and rude. Being clueless and rude makes him a prime candidate for being disinvited.

I suggest accepting or denying builds on legal grounds wherever possible
"I am DM. My word is Law. Legal is what I say is legal. Your feat is dismissed."
There, perfectly legal. Of course, if the game is supposed to work, you'll give an explanation. "I think this rule is broken", is a good explanation, if you take the time to tell them why you think that, it's a great one.
Allowing a cleric to use divine metamagic and persistent metamagic is not "upping" the power of the cleric - it is merely allowing access to certain splatbooks. The power of clerics may increase as a result, but fundamentally we are considering an issue of access to material.
That is not true. We're not banning clerics from using that splatbook. He's free to take all the other classes, prestige classes, feats, spells, magic items, whatever from the book (provided they aren't broken and therefore banned). We just ban that single feat - for everyone.
And specifically saying that divine metamagic can be chosen and used with persistant spell most definetly means upping the cleric's power, since it directly means opening the door for him to cast divine favour, divine power or righteous might to last the day.
I once played a cleric with persistant divine power and persistant divine favour (back when persistant was only +4) as part of a "clerics aren't walking band-aids any more" project (basically, I showed the AD&D-marred players that clerics aren't weak sidekicks that can only heal) and it wasn't even funny. The DM soon approached me that it was too much, and I readily exchanged persistant with another feat (quicken).
Assuming that those splatbooks are otherwise allowed for other characters, it would be pretty unfair to exclusively deny access for clerics, don't you think?
Of course, but noone suggests to deny clerics access to whole books based on a single rule that is banned for everyone, not just clerics.
