I don't really think the
"this tag is meant particularly for non-yuri series"
part should be there.
It kind of states it as a fact, and there's a good amount of yuri series that can have this tag.
Hmm, would it be more acceptable to say, "this tag is meant particularly for series without a yuri tag"?
Not sure if your point relates to semantics or something else, so pardon if that's not what you meant.
