I think, at least the way I understood back in the old days from that old site 
, the “Don’t yuck my yum” is more about very distinctive foods, not so much about the same food. Like you said, this is a food discussion board and we are all passionate about food, so disagreement about what is the best fish taco or burger or whatever is unavoidable.
The “Don’t yuck my yum” is more like…statements like: I hate natto and anyone who likes natto has no idea what good food is like – pretty much bashing something you are not familiar with or even tried.
But the truth is that … it is a suggestion, not a hard rule. We recently have a disccusion topic where pretty much everyone bashed the raw water movement.
