Genres/subgenres should be logical

(This is partly from a previous post, but I am afraid that it has been lost or ignored.) Three major problems with the relationship of genes to subgenus, and vice versa: First, If a subgenre/keyword has a genre as an addendum, that specific title should also have that addendum as a genre. This is basic logic and the principles of outlining. A keyword/genre is a “sub” point to a genre, a “main” point. There cannot be a “sub” IF there is not a “main." For examples, If a title has parody-comedy as a subgenre, should it not also have Comedy as a genre; if a title has monster-horror as a subgenre, should it not also have Horror as a genre; if a title has soccer-sport as a subgenre, should it not also have Sport as a genre; etc. Second, the guideline says, among other things, keywords should avoid: “Repeating genres: For example, we have the genres Romance and Drama so you can submit these as genres to the title rather than submitting the keyword romantic-drama.” Yet, we have romantic-comedy as a subgenre when those titles should just have Romance and Comedy as genres. If a title has Romance and Comedy as genes, that make the romantic-comedy subgenre redundant. An advance search combining the Romance and Comedy genres would give you ALL the Romantic-Comedy title just as an advanced search combining the Romance and Drama genres would give you ALL the Romantic-Drama titles. Third, until the genre list is expanded (probably never), the subgenre list needs to be expanded. Some vey prolific subgenres are now relegated to the “Other” category. Fo examples, “melodrama” and “soap opera.” They should be subgenus. namely, melodrama-drama (can’t avoid The Name Game song) and soap-opera-drama. Are there others?
