^The thing is all the entries you mentioned already have sensible parent entries. Given that we have entries like Forced Meme, I'd prioritize making the entries you mentioned as subs as you requested if it were my call, but the style guide specifically states that parent-entries should be considered with the following:
1) An entry about another meme or event that spawned this meme
2) An entry about a subculture that is the main subject of the meme
3) An entry about a person that is the main subject or creator of the meme
4) An entry about a website that is the exclusive host of the meme
The entries you presented all seem to be following the rules. I suppose for now just tag Forced Meme with the names of the memes you want subbed under it :/
