No other Dungeons and Dragons setting is as popular as the Forgotten Realms, and no single author has done more to shape that world than its creator, Ed Greenwood. Greenwood invented the Realms, has written dozens of novels and adventure modules set in them, and answers fan questions about the unexplored corners of the Realms on social media. And in a quintessential example of the internet being the internet, this has resulted in Greenwood giving canon explanations for what several different DnD races' breast milk tastes like.
Before we all have a giggle, a reminder - humans are mammals, mammals feed their babies on milk, and the only reason there's any furore around breastfeeding is because of taboos around feminine nudity and bodily functions. Breastfeeding is healthy and natural and, if we lived in a society that was fully supportive of people who give birth and babies, it would be so unremarkable that there would be no frisson of taboo around it.
With that being said, here's what Ed Greenwood has to say about different DnD species' breast milk:
Elf and Drow milk
"Drow breastmilk, thanks to those who produce it having centuries of exposure to cave fungi and molds and the faezress, tastes a little more mushroomy than minty elven breastmilk. To any humans who sample it, the result is a little more chalky, and ever so slightly tart/hot (the same way those tiny cinammon heart Valentine's Day hard candies have heat), but to elves who sample drow breast milk, it tastes sweeter than it seems to humans (and far less minty than their own breast milk). Interestingly, to dwarves, both elven and drow breast milk taste a lot like (original, unsweetened) licorice."

Githyanki milk
They do [lactate], the breast milk serving to nourish for rapid growth, building of muscle tissue, and healing of organs and sinews. I am told (no personal experience here) that the taste is akin to rich chicken broth.

Griffin milk
Yes, griffin milk is a thing, and it tastes like cream cheese or mild Gouda (stronger flavor as the mother gets older).

Half-dragon milk
"Male and female half-dragons in the Realms all have nipples, but how much in the way of breasts they have beneath them depends on individual genetics and the species who are the other "half" of the half-dragon's parentage.
For humans, elves, halflings, dwarves, gnomes, orcs, goblins, hobgoblins, kobolds, and centaurs, the answer is yes: noticeable breasts. All of the half-dragons resulting from such unions will produce breast milk that speeds the growth in size and maturity (including, yes, permanent teeth coming in) of young suckling on them, so the breasts aren't mere "decoration for artists to enhance portraits with."
However, some half-dragons will be buxom, especially if they are fat or burly of build, and some will be sleek indeed ("flat" in human parlance). So a particular half-dragon character can look like almost anything."

Dwarf milk
"Unlike human breast milk, wherein alcohol level mirrors the blood alcohol level of the mother, dwarven breast milk contains NO alcohol: dwarves subsume all alcohol within their bodies (they can generally drink a LOT more strong drink than humans before becoming really inebriated because their bodies deal with alcohol differently than humans).
Dwarven breast milk generally has a higher fat content than human breast milk, but both sorts of milk are primarily water carrying a mixture of highly nutritious substances (such as fat, minerals, carbs like lactose, immune cells from the mother's bloodstream, body-needed substances we call "vitamins," and proteins). This mix aims to impart great nutrition, but its precise composition varies with the mother's diet, the baby's age/development, the climate, and so on."

I'm not about to psychoanalyze anyone involved in this, but I will make some observations. When a famous fantasy author starts answering questions on a taboo subject, inevitably people want to play along. Greenwood got more follow-up questions in Discord, but only answered one more there that I can find. His response to the first question escaped containment as a meme, which is why he got the questions on X.com.
The Discord question that began this mini trend is written as though it's riffing on an earlier statement: "since elven breast milk tastes minty, does drow breast milk also taste minty?" That suggests that Greenwood had already made an out of pocket statement about elven breastmilk, but I can't find anything to that effect online. The original questioner even states in the same forum that 'minty elf milk' was just something they'd heard about from a friend.
So, if you want a way to interpret this whole series of events without considering any paraphilias, you could simply see it as a cycle of people being amused by Ed Greenwood's frank answers to unexpected questions, and Greenwood responding to (some of) their niche questions as writing challenges.
If you'd like to join an online community where the main in-joke is a weird fixation with pigs, not fantasy breast milk, come and join the Wargamer Discord community!
For a look into internet communities that definitely have some kinks, I recently wrote an article about the secondary interests of all the Warhammer 40k faction subreddits - you can read it here.
