Why didn't DD reveal Voldemort's identity?

Pippin:

A boggart dementor can be controlled with a simple ridikkulus. A real dementor
will suck your soul out while you're trying to think of something funny about
the worst day in your life. And Voldemort was very good at providing people
with days like that.

But he was always careful to refrain from taking public credit for deaths and
disappearances until he had built enough support underground to post the Dark
Mark with impunity. Until then, he was quite happy to have outsiders think he
was no real threat.

Alla:
I disagree with Marion on details, I certainly do not think that it will be as simple as that – just laugh at him and he will go away. But I do agree with her in principle. Sure, I think that  he may not go away just because people will laugh at  him, but to me  what I argued upthread has the potential substantially diminish his influence. Sorry, Pippin but all of the explanations of why Dumbledore did not disclose that Voldemort is Riddle to me  do not hold up.

Dumbledore was afraid that it will harm his investigations? But as Magpie said Dumbledore is the guy who knew Riddle from the beginning and can go straight to the source if needed, so I am still unclear as to how it will harm his investigations.

Of course I find the explanation that Dumbledore was afraid that it will harm other half bloods and backfire on him to be unconvincing as well, but I already attempted to address it upthread. I think carefully chosen words of this story will be risk very well worth taken.

Now, I CAN possibly see the explanation that Dumbledore would be afraid that Voldie Tom would just simply kill off all people who knew him as Riddle. I agree that it will be very much like Tom, except, well it does not feel very Dumbledore like to me.

Now how many people still know Tom as Tom? I would bet that we can count them on the fingers of two hands, if that many.

Sorry, but after book 7 Dumbledore does not strike me as a guy who would worry much about few lives lost if greater good comes out of it.
Before anybody asks, no I do not think that Dumbledore is a murderous maniac like Voldemort, no I am arguing  in there is no good or evil only power thing.

But yes, if some people fall along the way and say WW could get rid of Voldemort, I do not think Dumbledore would worry much. 

The bottom line to me is this :

I am yet to read convincing argument as to why it is not worth it that Voldemort followers who believe in the "purebloods rule" will know that their leader is not pureblood since they have nothing but absolute contempt for anybody who is not pureblood.

Pippin:
Voldie's original servants, the people from his Hogwarts days, already knew his
real name and background. But that would be more than outweighed by the
knowledge that he was the Heir of Slytherin and had proved it by opening the
Chamber and being a parselmouth. Any DE incautious enough to imply the opposite
would have been made an example for the others. If Voldemort wanted the name
Riddle forgotten, they'd forget it -- anything to prove their loyalty.

Alla:

Are you sure about that? Sure, they probably knew his name. But did they know his background? Somehow I doubt that Tom was going around advertising it. But if canon says so, that certainly would strike a hole in my argument. And wouldn't the fact that he opened the Chamber prove to them exactly that – that he is a Pureblood?

Pippin:
The new recruits were drawn from people who already hated Albus Dumbledore and
everything he stood for. Why should they care about anything he had to say?
Ridicule from him would only show how blind he was to their master's greatness.

Alla:

I am not saying that Dumbledore should have gone for ridicule either. I am saying he should have gone for the facts, that's all. I mean I think laughter always helps, but not saying that it will have made Voldie just go away.

As to why they would care? Eh because they think that half bloods should not be in charge?

In fact, who says that it necessarily should have come from Dumbledore? Although I see no reason why not. Just give a tip to Rita dear, although since Dumbledore taught him I guess it will be more credible coming from him.

JMO,
