Why do people say that sprouts are horrid as if it's the people who love them that are in the wrong?
Perhaps because people who don't have part of their sense of taste missing tend to have had sprouts forced on them in childhood by someone who does, and are rightly disgruntled about the whole thing.
Or because
SCIENCE says the nasty bitter taste is there, it's just some people can't detect it. That's the closest we're going to get to objective truth on the matter.
As a genetic lack of a receptor, I see it as equivalent to colourblindness: I don't go around accusing people of being *wrong* for going on about things being purple rather than blue, or arbitrary differences in the shades of $generic_poo_colour, so it's only fair they accept my word for it when I talk about what sprouts really taste like. Which doesn't preclude them loving the things, any more than being colourblind precludes me liking primary red because I think it's a nice understated dark colour. We just have to accept that we're being weird.
It's one of those things like delayed sleep phase, which is a random biological thing that people can't help, but society - lead by the people who don't have the thing - has attached a negative value judgement to, as if people who can go to sleep early, or who can't taste the bitter of green veg, are somehow superior to the others. I think it's only right that we make noise about how these things work, in the hope that more people become aware that they're innate things that can't be helped, and stop making people miserable trying to make them conform to someone else's biological convenience.
