I'm not familiar with all of the fics mentioned, but are any of them labelled as Esleworld or Alt-Universe? That might solve some of the problem because if it is labelled as an Esleworld or an AU story then people can't readily complain that our Clark wouldn't have more than one love because the story is not about our Clark but some other Clark.
After all, a story that has Clark sleeping with Lana or marrying before Lois definitely is not about L&C:TNAOS. It is either an AU or an Elseworld because that didn't happen on the TV show. Now if you were writing about Smallville, that's a different story and would most definitely fit with that show
