That's fair enough, I probably should have contrasted 'love' vs. 'hate'. The difference in magnitude wasn't intentional.
I meant to point out that the negative is more often treated as "wrong" or something to fix while the positive is more often simply accepted. I think this is true in general, at least in western/english conversation. But the coriander conversation is notable because apathy or plain dislike for the flavour can be "backed up" with the definitely true genetic explanation. Although in that sense, you actually "can't not like coriander".
