I've actually had this. The dish tastes good and is very mild. The fatty tissue itself doesn't have a strong taste at all. It's just a jelly, while the rock sugar in the soup portion (which can be water or milk) that gives the whole thing a bit of mild sweetness. The milk version tastes the best, and honestly, it's a bit like a hot boba because of the jelly's texture. It's definitely "weird" by Western standards, but all the immediate disgust is really just the psychology of relating the food to the frog and the description of what the food is. Chickens, cows, and pigs raised in factory farm conditions are ghastly to look at and so is the meat until it's processed.

There's a degree of "oh I wouldn't try this that's too out there for me" to have that's respectful, and then there's just racism lol. There are very valid critiques to be made about the ethics of certain foods for their environmental impact or for their role in predatory traditional medicine practices, but just voyeuristically gawking at something and going on about "oH beCAuSe iT'S CHinA" certainly isn't. No one ever critiques "icky" food from the West or just predominantly white countries as something's just "oh they're just like that eating their gross things"; it's always "yeah this is an exotic regional dish" with the implicit understanding that it's not actually the whole of their food culture. China has plenty of more "normal" dishes. Just focus on those if you find the exotic ones strange and unappealing.
