I've never 'got'

I dig all of those bar coriander and anchovies (I'm a vegetarian) you can't compare one with the other though, when fresh it's just so powerful and it will take over all the other flavours of a meal, perhaps my palate is not sophisticated enough to appreciate it.

No, it may just be that you taste it with unusual intensity. Tastes differ (if often only slightly), and if you think it tastes soapy, you may just taste one or several particular flavour components to make others seem less prominent.
