What they are saying is that you can make yourself enjoy a field _at all_, in which you can then apply taste. For example I don't like whisky, but that's not a matter of me applying "good taste": I would never claim that whisky is bad in general and if I really tried I'm pretty sure I would start being able to enjoy whisky and separate the good from the bad (at least subjectively).
One time on 4chan I mentioned I liked how users on HN like to pepper their speech with little math words like so: "Love is orthogonal to distance, modulo trust, and the parameters aren’t marginal". People wouldnt believe me this was normal talk. Case in point. Although this was more prevalent on HN about 10 years ago. Or maybe now as well. I dont read comments as much these days.
