I agree! My point being that if taste is subjective, defining something taste-related as "wrong" (washing the moka, putting pineapple on pizza, etc.) is also silly.
Do as you please, eat whatever you will, if it diverges from tradition or received knowledge and you're happy about it go ahead and enjoy!
I don't know how one can question taste... it's taste after all! It's subjective.
What I'm hearing is that you don't like bitter espresso with sugar. This is to my taste, and yet, I'm not questioning yours :)
