What was Tolkien's stance on ladybeards?
Tolkien was quite clear that female Dwarves had beards:
Tolkien answered this question explicitly in other texts. In The War of the Jewels ("The Later Quenta Silmarillion: Of the Naugrim and the Edain", written ~1951), Tolkien wrote that
no Man nor Elf has ever seen a beardless Dwarf - unless he were shaven in mockery, and would then be more like to die of shame... For the Naugrim have beards from the beginning of their lives, male and female alike...
In The Peoples of Middle-earth, Christopher Tolkien says that a similar statement was present in an earlier draft of Appendix A as well. As these statements are entirely in agreement with the canonical evidence cited above, the conclusion that Dwarf women had beards seems inescapable.

While the beard is regarded as a symbol of dwarfdom, here is my argument against it being such.
DF is, first and foremost, a work-in-progress reality simulator. It can be also used as a game, but a perfect simulation of creation is clearly it's primary purpose. In real life, female humanoids, for the most part, lack the ability to grow a good beard. They do, in some cases, have facial hair, but not of dwarfy length. So, I put it to you that realistically (Unless dwarves have a different balance of hormones and such to us, which Toady has yet to specify) female dwarves would also be mostly incapable of beardiness.
As such, to say the beard is an important part of a dwarf would be to intentionally segregate men from women in terms of status. Alcoholism, justified. Depth-delving, justified. Why? Because both men and women can stake a claim to such symbols of dwarfiness. Dwarven women can be just as awesome, just as ass kicking and just as insane as men. Do not look upon them as less for their bare chins.
Of course, this is all just speculation assuming that by real-world parameters, dwarven women cannot in fact grow beards.
You're arbitrarily assuming that dwarves have a similar degree of sexual dimorphism to humans. They're a fantasy race. Why would you do this? It's silly. And besides, there have been women who have grown relatively dwarven beards:

We can resolve this by using a bit of armchair evolutionary biology.
This can be fun, but ultimately, relying on scientific rigour to determine something that is purely fantasy is folly. I would prefer to take a more philological and philosophical route.
The classic image of a dwarf is that of a short old man with a long beard. This association is so strong that when one considers the existence of female dwarves, the problem arises:
You can't have half the Dwarven population walking around beardless. That would be like having a race of satyrs, where all the females have human legs and no horns. They can't really be called satyrs, can they?
Tolkien was the first (as far as I know) to attempt to solve this. His solution was to give female dwarves beards. As the father of modern fantasy, I'd say this is pretty important.
So, why are people resistent to this idea? It's pretty easy to analyze:
1. The idea of a female having a beard gives some people cognitive dissonance. They're squeamish about the idea because it's contrary to what they're used to, and by human heterosexual standards, it's hard to imagine a male finding it attractive.
2. In the case of many RPGs, it's for the sake of marketing. Both for appeasing the squeamish folks and for the potential of making female Dwarves "sexy" along with other races. (And, well, the people who want this are just kind of sad. And probably adolescent.)
3. The idea of female dwarves having beards seems goofy and humourous. I see nothing wrong with this, and if anything, consider it a point in favour of them having beards.
All in all, I'd say beardless female dwarves are a total cop-out, and the 'side-burn' compromise is even more of a cop-out (seriously, guys? laaaame)
I propose that, to Dwarves, the term "beardless" shall have a negative connotation, meaning foolish, effete, cowardly, or confused, depending on the context.
